Talking Stuck on which way to go

I really need to make up my mind on which way to go with this NA build............ purely a street car it will Hardly yo Never see the track

Big Bore Boss Block/Stroked 323ci
2V: ported tfs 195cc heads, port matched vic jr and elbow, really wanting an oval tb so it'll breathe more, custom cams, etc
4V: ported 4v heads, probably ported cobra intake, oval tb, custom cams, etc

5.4L Block 330-331ci
2V: same ported tfs heads, 4.6 to 5.4 adapters with same ported intake, custom cams, etc
4V: same ported heads, hoping to use the super cobra jet na intake and tb, custom cams, etc

5.8L Block 351-358ci
2V: same as above
4V: same as above

What are you guys thoughts on this?

I would go the most cost effective route since no racecar, but thats just me.
Really doesn't matter, it will be fast/faster/fastest set up. And fuel mileage will be crappy/crappier/crappiest respectively.

Not sure. They all sound good.
I'd probably go with the one that you can find the most parts for. Headers for one.
Otherwise you'll be doing a lot if modifying.

Your about to spend ALOT of money!! if your goal is to be faster then the next guy your going at this wrong. BUT if your like me and just want what you want then I suggest going the 4V route with ported heads, custom cams with the largest bore and stroke you can throw at it safely. Going NA forget the 2V heads they will never flow enough to make you happy.

Yes I'm just like you so to say, I was going to go fi, kenne bell or twin turbo, but told myself that I really did not need that as it'll never see the track to fully use it, and the thoughts of high compression na build cam to mind, not worried about being faster than the next guy as I once was, those ported 195cc heads should be more than amazing without ruining them with over porting, cant really say which way I'm leaning more towards

Definitely going to cost me but oh well, for what either set up will run me I could build 2 fi setups almost

Also was suggested going the coyote route, and using the scj intake and tb highest compression on pump 93, and I was told that the 5.4 with the scj intake would not fit under the stock hood, if that be the case I have no problem with the 00 cobra r hood, just don't have for the extra cowl hoods

I doubt I go the coyote route, even tho it will be nice as hell, unless I could use the coyote bare block and not have to worry with all that is necessary for the swap, but I highly doubt it

I wish you luck. You must have a lot of money to spend because NA is a very inefficient choice. Again, good luck... you will need it.

Actually NA is the MOST efficient choice. THey are more efficient than any boosted motor out there. The more you make NA, the way more you will make IF you put boost on it.

To the OP...make up a ET goal for what you want, and then you can decide how light you want the car and how much you will need to get there. If you just want bragging rights on power...then get the most cubes you can get, and get the best heads out there..ie Ford GT/GT500/Cobra R heads, get them ported and run a sullivan intake. But look to spend around 15-20k easy if you want the bassest one out there...

Agreed with you on the most reliably efficient way, but aa far as cost goes...... nahhhh, it doesn't have to be the baddest, I just want it to run strong and be fun car, as far as an ET I'm not sure at all being, this will never really see the strip, still have to decide on if it'll be 2v to keep the architecture of the car or if ima build the 4v, but either way I know I'm going to be happy with it, I mean I'm not trying to set records or anything

I've thought about the GT heads, not the cobra rs or even the gt500, if I go 5.4 I may have it bored to a 3.7" and run one of those heads I'm not sure

A 5.4 bored and sleeved with one of those heads ported, custom cams possibly the scj intake would be Stout as hell

Your car will be just as much fun to drive with a 4.6 and blower/turbo as a bad ass NA motor. I have a 400 CI SBC in a 1942 Jeep willys making well over 400 HP NA and a 383 in a 1974 corvette making 457 HP NA, but my boosted 4.6 is just as much fun. If you are staying NA there is no replacement for displacement. Remember that with a solid NA build you should be able to get roughly 1.15 HP for ever CI. You certainly can make more than that ratio but that is on par without dropping cash like it's your job. Therefore, I would go the 5.8 route.

Yea true I could have a fun car with a blower or turbo, but id end up going overboard! I know me, and there is some talk about getting a 5.4 block and sleeving it and getting it to a 5.8

Wish I could get the new ford 5.8l block for cheap ever I've seen is 4k+ just for the block itself, probably because it's an aluminium block,

+1 to everyone that is saying it will cost tons of money...

Here is a dyno graph picture of my friends N/A 01 Cobra. He has an aluminum 4.6L that was Bored & Stroked, runs on 93 Octane @ 12:1, with ported GT40 heads, custom headers for his engine, that's all I recall about now. I don't remember his full mods & build list to his motor but it was fucking huge.

So far the most power he made was at 644rwhp & 606rwtq @ around 6k rpm, his motor is made to rev to 8,500 rpm... but he under anticipated the power & his intake was restricting air flow, so you can see it stopped making power around a bit past 6,000 rpm.



He spent over $40,000 building his car, that's including his trans, built irs & suspension. Most of which he said was into his motor.

Bow down to him! I by no means will spend that in a a motor, I salute him and that is amazing! Ill prolly be at 12:1 with a similar build but NOWHERE near 40k
