this summer i plan on over hauling my 93 gt. i'd like it some what drivable and some power when needed. (350-450hp) i'd like the higher end.

so far what i've planned is:

stock block stroked to 347 + bord .40
edelbrock upper and lower rpm 2 intake
AFR 185Cc and 58Cc heads with 1.7 rocker arms
and other bolt on CAI, underdrive pullies, 1 3/4 LT..ect.

i don't plan on hooking the smog back up. i'd like to keep a/c.

from the researching and looking at other people's builds looks like a custom cam would be best but i haven't a clue where to go for that?
i'd like some lope (i like the power band of comp cam's XE 266 but it's off the shelf cam and isn't made for a 347. some say that cam is way to small.)

i also am not sure on the horsepower i'll be making so idk the: MAF sensor, throttle body, injectors (i've seen like 30 lb?) ?

i know alot of people like Trick flow heads better then AFR but i want to stick with the AFR ones. another issue i've stumbled on to is that the heads MAX lift is .600 the cam i mentioned with the 1.7 rocker arms will put it's lift at
.578/.590. is that clearence okay?

piston clearence is another problem i think i'll run into. i know i'll need 2.02 valve reliefs just for the heads.

please help anything is welcome
sorry for the letter

Do the 347, do TRICK FLOW heads....everyone wonders why they don't make power with AFRs and its really simple...ill get into that later though. Get the intake done by TMOSS because he will match it to your needs. Cam you're gonna want a custom...Bullet cam's, Flow Tech Induction, Bret Bauer racing etc. If you're doing a stock block just go. 030 over in case you need to clean the cylinders way down the road. The lift rating on the heads is because of the springs. Change them when you do a cam. If your springs are matched to your cam then you will make more power. Trick Flow 190cc FAC heads are great for the money.

If you buy AFRs, factor in more money to put good hardware in those heads. The stuff they come with sucks.

i looked at TF 190 heads they look pretty close just alittle bigger w/different springs. is putting new springs on hard? what would i need to know for someone to be able to make a custom cam?

thanks for the input.

i've heard about some of that thats why i was gonna get the rocker arms. figured why not go bigger while doing it?

The custom cam manufacture, generally tells you what rocker ratio is best for that cam. And the cam should be the vary last part you buy

[e3sean]

your typical 347 is going to be 4.030 bore.

whatever head route you want to go is going to determine what pistons you buy with your kit so buy your heads first.

buy a bare set of heads though or a used set cause whatever custom cam you go with will determine what rockers and springs you will need to buy. and there is no reason to buy a complete set of heads just to throw a bran new set of the wrong springs to the side.

your gonna have to decide if you want to go with a solid roller or a hydrallic roller. what rpm do you want to rev the motor to? with a stock block id say keep it under 7. realistically whith those heads and a mild cam your shift oints will most likely be about 6500-6700 till it runs out of air.

with this power upgrade what are you going to do about your transmission and rearend/suspension?

some of the custom cam companys are, Comp , Ed Curtis, Schnyder, Bullet, just to name a few popular ones.

the machinest that gave me the quote on stroking my block said he would need the cam.. idk why. it will be a hydrolic roller. i want to stick to 1.7 rocker arms

i'd be getting a new tranny currently doesn't have one.. put that t5 in my aod.

suspension- for now sits on stock everything. i'd lower it .5-1in all around and stiffen it up. rear i'd do a 5 lug conversion while putting in 3.73's

shift points would stay lower i keep it under 5500. usually shift at 5k at the latest racing. otherwise 3000m or 3500.

shifting at 5500 on this build will be wasted power.. dont be afraid of the rev (unless its above 7k ) machine your block to how you want it.. buy your bottom end parts.. then buy the trick flow top end kit..

DONE

i'm not sure that will give me the power i'd like?
