With a choppy cam and a radix you'll porbably get blower slap.

 

Other than the blower, have you done any engine mods?

Either way, from what you've posted so far, I'd keep the intake lobe fairly short in duration, but go big on the exhaust. For such a small engine, I would stay well under 220° on the intake, but go over 230° on the exhaust. Then install where the intake lobe is more advanced than normal. +5-7 would work well.

 

Sure will, especially on a 4.8L. That gets annoying after a bit.

 

well i have headers,ported tb,coldair,servo,np tune,3in xr1 catless
next mods are 8psi pulley,icebox,4.10 tru trac,cam<next

btw whats blower slap?thanx guys

 

With a choppy idle the blower will make a noise from the gear clash internally. It isn't hurting it, but it makes a weird noise. Trust me, the GT2-3 with your setup would be a thing of beauty. Due to the 294 cubes you have, it might actually lope some. You might even consider the LS6 cam. Odd enough that damn thing suprises me in everything I see it put in.

 

I agree the GT2-3 is a great cam and yes the ls6 cam is probably the best all around cam that has ever been built.

 

Had a chance to dyno this weekend in cold weather. 381 HP and 375 TQ out of the little 4.8 with its GT2-3. Pulley is a 4.1 inch wagon wheel and made 8 pounds.

 

wow bro thats badazz^^^i have a 3.70 pulley making 7 psi

 

about how much horsepower would a ls6 cam give me?
