1st post - building a 351w -

chgovfk · May 18th, 2011, 11:36 AM

Hey everyone -( I own an 07 Gt ) - but I also have a 1993 4cyl mustang coupe -that I'm putting a 1971 - 351w in it that's .30 over - new pistons / 4 valve reliefs /slight dome (but basically a flat top) / stock rods - and I have the new edelbrock E -Street heads - 60cc chamber / 170 cc intake - can handle anything less than a .550 lift - ....it will be converted to stick (TKO) ....and I can 'run' any rear end gear ratio I want - ....I just bought a 5.0 rear end out of junk yard -...anyway - the BIG question ....

I'm thinking either of (3) three cams or ?- I've been looking on all kinds of forums / called comp cams etc ....and the only thing I really learned - is that there all kinds of different ways to go - the guy at comp cams basically said an opinion on ea of these three - with running issues - I was wondering what you guys thought?

Comp cams said - Magnum 270 - rough idle (which is good) - good vacuum - less power - ticky lifters -

Thumper cam 35-600-4 (the smaller of the thumprs) - gd power / and TQ - and will sound the best - but no vacuum -

XE 268H - best TQ and power over all - a little ticky -

With the 'new' heads - and this being a street only car - I'm want it to be street- able - but what the heck.... why not make it sound lumpy and bad/azz......I'm thinking the magnum 280 ...my friend who's a ford tech and an engine builder wants me to go to the Ford racing 'letter' cams - I have the mutha thumps in my 07 gt and I love them - but they are more for sound (but have punch) - the project car will run pwr steering / brakes and air -.....I want to start building this puppy - anything you guys can help me with would be great .....

Lol!!!! At a ford tech wanting to run a letter cam in a 351W. Those cams are junk for a 302, and not nearly adequate enough for a 351W. They are only good for making lamp posts. I'm going to put a letter cam in my sons car, to make it slower than stock, so he doesn't hurt himself.

I had an XE274H, with a set of TW185s on my 351W, and it made 280 rwhp. I had way more head than you, and more cam than you listed. If you haven't bought the heads, I'd buy a larger intake runner head.

flattusmaximus78 · May 18th, 2011, 12:08 PM

Wowzers, does comp cams customer service just suck dick over the phone while they talk? And a ford tech suggesting a letter cam? Having a fast pushrod motor, or a bigger cam, and heads doesn't mean it's not streetable. There are 408's that drive like stock. It's all in the cam.

chgovfk · May 18th, 2011, 02:13 PM

Thanks ...
I already bought the Heads ......my boss surprised me after I won a $2.5MIL contract - said here's my CC - you can only spend $1k limit on Summit (knows I'm a gear head) - I was stuck?.....he just popped in and said this ...I'm at my laptop ....so I'm like F it .....I had them in my wish list w/10 others ......I was originally going to just re-work/mach shop the original stock iron heads - and those E streets were the only ones under a G note ....but hey they are technically free -
Anyway my Ford tech friend just had I guess great success with a E cam - or was it X ...I don't know .....I'm thinking a comp cam would be best - I have the mutha thumps in my 07 and I really like them .......and ya the comp cam guy wasn't too much help ....I was laughing out loud when I read your comment.....

i have seen the extreme energy cams get good results. 351's are for big numbers so you have to focus on moving large amounts of air or you wont make good power, the letter cams work ok for the 302 but you are gona be moving way more air if you build the negine right, if you want to run an out of the box cam thats cool but if you really want the best results go custom grind. also make a plan now for what you want from the motor and start with that, or in the end you might have just bought parts that at may be wasted money

nxcoupe · May 19th, 2011, 05:06 PM

Is this going to be EFI or a carb?

95StangMX · May 19th, 2011, 05:38 PM

letter cam in a 351, its funny enough that he had "great success" with a letter cam in a 302, unless it was in the early 90's.. . Kinda sucks that you already have the heads, you might try to post them up and find someone to trade you for some bigger ones.... The whole point in going with a 351 is cause you can stroke it further than a 5.0, so way more cubes, and they will hold more power, if you are going to be making under 4-500 HP you are better off doing it with a 5.0 block, you can stroke it to 347 so only 4 more cubes with a 351 in stock form, 5.0 rotating assembly is lighter, so is the block, and it will rev quicker making it faster on the street or track than a 351 with the same numbers on the dyno...sounds like you have a daily, why don't you save up your money and go with a 408, bigger heads, custom cam, and make that thing a monster!!!!

chgovfk · May 19th, 2011, 06:35 PM

it's going carburated -....I hear you 95stanglx - ....but like I said - I'm more of a body and paint guy - I rebuilt (on the cheap) a 350 for an actual chevelle SS.. a 72' back before college (like 20 yrs ago) - it was a piece meal Big Block car - w/a 71' dash - and even a mechanic who checked the wiring for me said hey ...that sounds good/tight ...but I forgot that it had the BB rear end gear - and Boom on the highway - although I limped it back to chicago?!? from Iowa .....anyway -

I'm out of my element - I'm on a pretty tight budget - but the motor will look like it had a concourse restoration - I just want a decent running good lopey motor to cruise with - if I was gonna make it a drag car then I'd let someone else build the motor ...I get heart palpitations just thinking of building this 351 myself - with what money I already do have in it .....!?!......just want something easy but with a little punch and lope -....but everyone on here does make me think wtf ....I have it all apart.......

chgovfk · May 19th, 2011, 07:42 PM

I keep trying to post some pictures of the project - no success....they are Jpeg's ....and I've squeezed them down to 61.0 KB's ....and compressed them - but that's the smallest my PC will go...any trick to this.....?
sorry I'm a newbie ....

horsepowerjunkie · May 19th, 2011, 08:22 PM

I ran the XE268H cam in a 351w with World Sr heads, RPM air gap, 650 holley dp, backed by an AOD & 3.73's. It was in a 86 coupe that I built for my wife. It had a slight lope, lots of torque & ran well. If I had to do it over again I'd go one step up XE274H. I think that would give it more mid range & upper end power. IMO.

dude read about those heads. the springs are GARBAGE google it. Destroyin shit serious

Ohsplat · May 20th, 2011, 12:51 AM

Hatch, which heads?

Ohsplat · May 20th, 2011, 01:01 AM

Does this seem a bit underpowered for a roller 351 with gt40 heads and 1.7 roller rockers? Did they tune it down a lot? 240hp seems low for a 351 out of a lightning.

ryanw · May 20th, 2011, 02:53 AM

Didnt some one post a link about those E edelbrock heads,,,,,Saying some thing about the springs breaking and your limited on what type of springs,and lift you can run, and you cant run a roller cam or some thing like that......does any one know what I'm talking about

chgovfk · May 20th, 2011, 12:16 PM

I researched it and it seems that people who bought the E street heads and wanted to run a roller cam - and they can't handle it - spring breakage - .....In Iooking - I guess (and I haven't totally confirmed it ) but you can buy up-graded springs from summit for like $130.00 and switch them out if your gonna run over 500 Hp/5500 rev limit - anyway ....I'm stuck with them .....thanks faststang91lx for the photo help....and HPjunkie - I'm really leaning towards exactly what you suggested - for sure a XE cam - I almost bought the 280 Magnum - it seems like the safe choice is the 268 - .....I just want low to mid end HP - but the 268 is what everyone said with the stock heads - so I want to bump it UP ...even with these E streets - they have to be at least way better than the stock heads ?!?....running a 274 just may be just the answer -

Some pictures of what I've up to so far -......

.....no pics ...I'm on photobucket ...( I forgot I had an account ) ...my IT guy here at work will help me Monday -.....I'm pulling the 4cyl out of the 93' tomorrow - funny story:
I was gonna trade the mustang junkyard guy out here in AZ the 4cyl for something - but I said F it - I'll put it up on craigs for cheap......thinking who the Fu*k would want a dual spark 4cyl - w/85k on it - well I was wrong.....I guy from Chicago who lives out here 'ran' right over ...so of course we ended up B/S-N for an hour -

.....seems his 17yr old son 'knocked up' some chick ....he just got a job to pay support (she's a 'piece' of work/no visitation) - but his 92 ranger has a blown motor - this will slide right in ...w/frt brackets switched over ( the guy just wants to see his grandson) ......he's coming over to help me pull-it ....and I'm loaning him my 'cherry picker' and probably helping him on his ranger?!? (if I have time) cause the story pissed me off.....
