how much HP/Torque? Well I may be buyingt me a 1994 Formula Firebird.
Here is what its got:
LT1 block
LT4 ported/polished heads
Eagle stroker 355 crank
Summit stage 2 rods
10,4:1 forged aluminum standard bore pistons
BBK caramacoat headers
BBK 58mm throttle body
K&N intake
Venom 36lb fuel injectors
Trick flow aluminum intake below
LT4 hotcam kit
Centerforce dual friction clutch with steel flywheel
SUMMIT CHROMEMOLY ONE PIECE HEAT TREATED PUSHRODS
MILDON PERFORMANCE OILPAN
HIGH VOLUME OUTPUT OILPUMP
HIGH FLOW WATER PUMP
160% LOW TEMP THERMOSTAT
HURST SHORT THROW SHIFTER 6 SPEED[/SIZE]
What kinda power do you think she is making, also what do ya think shell run in the 1/4 mile with everything else like suspension stock?
Thnaks,
Ben(You knowI miss the ole camaro 1994 since I got the chevelle)

The heads are a mediocre choice.
Summit stage 2 rods are most likely a step down from stock. The stockers are VERY VERY good as OEM pieces go.
The compression is a mistake to go so low.
The Venom injectors are a mistake.
The HOT cam kit was a poor choice.
"high flow waterpump" if it is the mechanical Summit sells then you got a stock pump
, if an electric it still flows less than stock.
A 355 is derived usually by boring a 350 block .030 over and using a stock stroke crank, the stock crank is better than most of the Eagle stuff.
The intake would be a hassle to use because of the fuel rail crossover, should not have any impact on OBD1 vs. OBD2.
Whomever tries to hate on my replies please take them point for point.
I know this post aint pretty but it is honest which to me is more important.

I would guess 315-340 rwhp, pending tune and setup.
Hmm. I have seen hotcam people with ported heads (depending on the port job) put down 330-350rwhp with supporting mods.
And Eagle cranks are better then stock. Eagle has a good reputation for 350 crankshafts.
I think youre being a little too hard on him, not everyone wants a superbeast and is all knowing like you.

Well I got a forged Lunati 3,875 crank laying at home and set of ross custom 396 40 over pistons, So I just need the rods if I really wanted to go big!!! I am just looking for a decent car because I am not planning on running the crap out of it!!! Ill take a look at the car and if I buy it ill just keep it this way until all of the chevelle is done and may drop it in it then. (body of the formula is not to good). Still 315-340rwhp is pretty good for a daily driver. And plenty to keep with a few porsches over here in Stutgart, Germany. Yeah since it a forged crank how will it be worse than a cast. Also everything can happen with rods. Doesnt matter how strong they are. (I know what you are saying) One of my good buddies had a lunati rods rip on him (now thats pretty hard to do because the engine was built by a very good engine shop too).
Also everybodys got their own opinion on things. What they prefer and what they dont like.
So you are saying the venom injectors are to big?
Also you say the compression is to low well I believe its plenty. I wouldnt go over 11,5:1 for a daily driver anyway.

Many years ago I made 350 rwhp with self ported LT4 heads, ported LT4 intake, GM hot cam, stock bottom end, and MAC 1 5/8" shorty headers with a stock tune. I still have the same heads and intake on the car today that now makes 430 rwhp. As for the 93 intake question, the car should already have an LT4 intake with the LT4 heads and you would not want to change that. The 36lb injectors are pretty big for the HP level you are looking at but a good tuner should be able to make them work, but they are not optimal.

Eagle's machining SUCKS the forged may be strong but if you ahve to pay for extra machining what are you saving?
If I were to replace a crank and stay 3.480 Compstar would be the lowend of what I would look at. I have never heard of a case of HP killing an LT1 crank so if it were going to "upgrade" I would make damned sure it was an upgrade.
Far as the HP thing, folks a lot more experianced than I will back me up when I say HP does NOT equal performance. You want to stick to low rpms like the pcm limits us too and stockish displacement then LT4 heads are not a particularly good choice, a popular choice yes but popular does not make it right, not even if people who already made that mistake swear by it.

Whats the point of power peaking in an rpm range that you will hardly ever see??? Will only hurt your times versus a curve that doesnt peak as high but has more area under the cuve.
