Ok heres the idea I've had for so long now and just been putting it off because of money issues. Now that I can afford to do it, heres what I'm thinking...

350 4bolt main (out of old suburban, thanks Daz)
It came with X rods and dished pistons but I'll be swapping those out for some forged ones.
LT1 intake (would my stock 48mm throttle body bottle neck this?)
Dart Iron eagles or the Pro 1's. Depends on money...
Cam to match the heads/intake, would be flat tappet
I have a set of pro magnum 1.6 roller rockers, those would work correct?
I would need to buy a new fuel rail, I have injectors etc...

I want to have a solid low 13/high 12 engine. I'd be happy with that. I have a few pieces for sale to help with my engine build fund if anyone is interested. PM me if you need something, TPI stuff, ported stuff, LT1 cam etc...
