Im very close to buying these but im curious if the 1" 5/8 primaries are going to hold me back. Im looking at the hooker super comps but they just look like a pain to install as I had a buttload of trouble with these SLP's as it is. Would this be a good choice for a vehicle putting 350 hp to the wheels? Im currently running 1" 5/8 shorties.

 

im sure they will be jsut fine, rememeber, smaller pipes, = torque, and to me thats a street motor ,

 

dad runs them on his motor, he's pushing closer to 450hp at the wheels. car runs 11's with a powerglide(only a 1.82:1 first gear)

 

Good enough for me, gonna do this when the income tax comes in then and probably go true dual.

 

excellent! true duals are the only way to go imho! i'll tell ya, if my dad had a th350 or something similiar in the car, it would be running LOW 11's or possibly high 10's. the car is wicked quick. his mph is in the 118 range.

 

So these will fit in with a LT-1?

 

Yes, as far as exhaust goes, its identical to all previous small blocks. They will work fine.
