Evenin' gentlemen. I have a few ideas I would like to bounce off of you and get your opinion.

Now this isn't happening in the near future, but I looking into different set ups for the ole 302, and have come up with two options....

TFS Street Burner kit on a rebuilt bottom end.

OR

FRPP crate motor(306, E-Cam, GT40-X's) toped with either a used Cobra manifold or a TFS Street Burner manifold.

Those two seem to be the most appealing routes. Here are some goals:

1) It will be a street car. I would like to make ~280 RWHP.. basically be capable of a low 13 second pass @ ~105 MPH on street rubber. The dyno number isn't important.

2) It will be emissions legal. I will be retaining the EGR(short tubes) and running a catted midpipe.

3) While I'm not trying to cut any corners, I'm not looking to blow the bank either. Like I said, I'm looking for a quick street car for my personal enjoyment. Longivity is key.

I know the E cam is easily bested. Would it be practical to slide a TFS Stage 1 cam in its place if I go with the create motor. Or for my application would it really matter? Also would a used SN95 Cobra intake jive well with the crate motor?

What do you think? Thanks.

if that's all your goal is a tfs h/c/i kit will easily hit that, should be able to hit 105-108 easy, I HAVE a mild h/c/i in my 89 vert, small eddy rpm heads, rpm 2 intake and custom cam with all the other normal bolt ons, and it runs 12's @108 , now figure a bigger tb and possibly maf to go with the new h/ci for optimum performance, also traction should be addressed to achieve the et goal

^ Alright, thanks.

Could I have my short block rebuilt for less than $1200? I know that's dependent on several factors, but say it didn't need to be bored and I stuck with a stock spec'd rotataing assembly... It's got about 165K on it now, and it runs greats, but I plan on keeping this car for a long time and then some, so I might as well have them freshen up the bottom end while they are there.

Would a 70MM throttle body be ideal, or would a 65MM do just fine? 24 pound injectors, and what size fuel pump would you go with? Should I have it dyno tuned as well?

Also, say I went with the crate motor... Would the SN95 Cobra intake manifold work well? Thanks again.

well , you could possibly do a overhaul which would be polish the crank, cut the ridge on the top of the cylinder bore with a ridge reamer, if a ridge exists, install new bearings and rings and hone it and buy new gaskets, when all said and done if you did the work, you'd have around 500 invested for what I call a scuff and dip motor/ overhauled, I've done a few motors like such for myself as well as friends and they work, but the best would be to have the crank turned, and block bored and new pistons installed and rods reconditioned and new cam bearings and soft plugs installed/ ect ect.....ring seal will be key to having good compression, so using quality parts and doing the job right, you'll be close to the 1200.00, last time I priced out redoing a 302 through my local machinest, parts/labor to redo the short block came close to 1400.00 and I could buy a ready to go short for that!!!

Good to know. Thanks, 46.

I've seen fresh motors with papers and everything for nearly half that cost, so I agree with you. I bought a fresh 355 with good forged internals for $1,000 even ready to drop in. Everything was fresh, including the heads (stockers, but lightly reworked with new parts).

At this point in time, it's fairly easy getting a sick deal on a shortblock or even a complete motor so I agree with MJ.

NoGo95GT

My 2 Combos-both on 95GT's
. Edelbrock E-Street heads, Comp cam XE264HR, Cobra intake, 3.73's 284rwhp/322rwtrq Best 1/8th was a 9.0@83 w/a 2.3 60 ft. Manual car

.Trickflow TW heads, TFS-1 cam, GT-40 intake, 4.10's 271rwhp/311rwtrq 1/4 13.1@105 AODE

Both were torquey and fun. Also, I had my 302 bored out w/new pistons(aluminum), new bearings, polished crank, etc for $450 from my local machinist.

^ Thanks, NoGo. It's nice to see real world numbers from your combos.

The GT-40 and the Cobra intake would make similar power, right?

Also, what intake/exhaust bolt ons are you running on your GTS? Is it tuned? If it's not tuned, would it be worth having it done, in your opinion?

NoGo95GT

Yeah no Problem!

The GT-40 is a tubular version of the Cobra. There really is no difference. They flow practically the same.

I run Summit shorty headers, BBK Catted H-Pipe, Pypes catback, CAI, 70mm TB, stock MAF and injectors. The car was tuned. But only becasue I wanted the hot idle-die syndrome removed. Other than fixing that, I do not think it was worth the $550. Maybe if it was a 331 or 347 or had larger injecors/MAF. It's something I would not do right away. See how the computer reacts to the cam first.

Sounds good. Thanks again.

I was thinking 24# injectors and a 190 LPH fuel pump.... Is that too much? Also would a 65MM throttle body work within reason?
