350 with around 9.5:1 compression
XE268
Vortec heads, behive springs, ect. machined for added lift
Edelbrock manifold

now this is where i get a little off course. i wish to stay with the LTR. anyone that doesn't agree, please don't waste my time.

would i be better off using the ASM runners, or saimeesing the base like madmax did. i like that setup more, because it looks bone stock, but i guess with a vortec setup, that won't matter much.

this motor is for a street driven S10 Blazer, so the low end torque is key. i don't care much about power above 5000rpms because it will almost never see that. thanks for any input you guys can provide, Jim.

 

What are the specs on the 268 im too lazy too look them up(they should have been here if u wanted honest critiquing)

later

the stock setup was designed for a stock 305 and works well with a 305. you will see nice gains by replacing the runners and lower intake

it is expensive though!

 

AS&M runners with an aftermarket manifold. I assume those are iron Vortex style heads. If aluminum bump up the compression ratio.
