When Westech Automotive built the 302ci LS1 what parts did they use to achieve that displacement? Crank, rods, pistons ect. I read somewhere that it has a 4.00" bore and a 3.00" stroke but I cant seem to find any info on the internals. An aluminum block (3.90" bore) LS1 with a crank from a 4.8l truck (3.268" stroke) = 312ci. So again I am just wondering what combination of things they used to get that displacement.

Good question.

I also read on the link you provided that the engine had heads; [Quote] "Specially modified LS6 cylinder heads (Advanced Airflow Engineering)

Anyone ever hear of this company? I have never seen anyone on the LS1 boards even use heads from this porter...

Advanced Airflow, Ron Sharp, Detroit area I believe.

That motor's final combo was a custom ground CompCams solid roller, LS6 heads, JE pistons, Dyer billet connecting rods, and I think it was last running a crankshaft out of a 4.8 motor. The block was a 3.900 stock bore or a 3.905 clean up bored motor. Cam was like a 250/250//112.

I drove the 302 and it's a nice and neat car.

How did you get to drive the 302 Camaro? <img src="graemlins/gr_hail.gif" border="0" alt="[hail]" />

www.westechauto.com is only 70 miles from me. I had some work done on my car there last year.

Thanx PSJ, so it was a 4.8 crank. When you drove it did it feel down on torque? They say 435hp but no tq #'s. I'd be interested to see a dyno graph of that motor (or similar displacement) vs. a 346ci to see the hp and tq curves and what rpms they are at.

Interesting to know. I've never paid attention to the 302. I'm curious also as to how high up that motor made power.

Felt good above 5500 rpms... But I'm kind of spoiled, it felt a lot slower than my car.

That 435hp is from the first cam, and that's not rwhp. <img src="gr_stretch.gif" border="0">

i believe BradWS6's LS6 heads in his 382 stroker were ported by them and he was going 11.1

Yeah I think so.

Don't take my comments about the car as negative, 375rwhp or so from a 302ci is very very good. The car was built to be very drivable. By now over hundred people have probably taken the car for a ride, and it started up everytime. It also did a leg of the HotRod Power Tour last year.
