I'm building up my 350 SBC. I bought a set of LT1 heads tonight and will have them slightly ported. I'm getting an intake (LT1) this weekend and will be modifying/installing it all on my Gen 1 motor.

I'm undecided on cams. XE 224/230 or 230/236? I was leaning towards the 224. Other mods will be:

-1.6RR
-Headers
-CAI
-Proper Tune

What cam and with each, what numbers should I expect (rwhp)? Thanks.

 

No point in porting your intake to 58mm if thats what you were looking at doing...

If you're going for a 'mild' port with higher mid lift numbers, I'd say go with the 224/230...

 

Oh no, by modifying I meant making it compatible to a Gen 1 motor (rear mount distributor, etc).

Cool, that's what I was looking at.

 

Do I understand that you are putting LT1 heads on a regular SBC? Not sure I have heard anyone doing this. Correct me if I am wrong, but modification will be needed to make it work. You will also have to use an LT1 or LT4 specific intake manifold.

If I misunderstood, then nevermind.

 

it actually quite simple shoebox...you weld aluminum chunks into the front and rear ports and your good to go

 

So how do the heads stay cool without all the coolant passages working?
