If i was gonna spend 2.5k i would be the GM 350 H.O in the summit mag for 2,499

No offense, but those changes won't net you 50 extra HP. Maybe 5-10 tops.

Do you have a dyno run graph where you got your 195WHP?

Would love to see it.

Love looking at a 4.3L torque curve.

haha yea i gotta find it somewhere. i was shocked the first run when i found out i only had 133 at the wheels.

While you are at it, find me what heads, cam, piston, rods, and rockers he used. For the cam I need to know the left and such and maybe what model number of it.

Did he port and polish the heads and what compression did he set it up for.

TheBrettster · 10-28-2006, 02:34 AM

well i believe the camshaft was from competition cams and the piston were from speedpro.

What size pistons were used? Did you up the compression?

What was the lobe size for the cam?

haha, to many questions for him. Before i decided to pull the v6, i bored it, put .030 forged pistons, used stock crank, rods. Put a comp cam in, not large enough to mess up the computer, used the roller lifters/pushrods/springs that was recommended for the cam and i used 350 aluminum roller rocker arms. Then, I bought aluminum 4.3 vortec heads, got a 3 angle vavle job, ported and polished. Throttle body spacer, upgrader MAF, and K&N cold air intake. I'm not 100% sure, but i believe i was somewhere around 9.7:1, which means still 87 octane, but i run 92 anyways. But i was getting like 12 mpg city, and like 18/19 highway. My freind put an LS1 in his truck, gets about 16 city and 24 highway. So i yanked the 4.3 and sold it for an undisclosed amount.
