Where should I start and with what?
I have a very good 350 that the intake manifold is not happy with the block. Im ready to pull the whole deal after 3x trying to seal stuff up. But... I want to keep the rear end. Parts are hard to come by so searching around here is moot. Can anybody say recently they did manifold, cam, headers, and efi or of the like and worked good? Not looking for crazy hp just clean up what I have and make a stronger runner. Thanka

Re: Where should I start and with what?
Thanks. Its an 89 and I was thinking of keeping the ecm since I just spent 200 to have it fixed. Was having fan issues. I'm having a hard time finding choices cuz alot of stuff isn't available or its going to be a while. And like you said lots of combos. If I have to change out the fuel pump I would. Im not looking for crazy hp. Dont want to mess with the rear. Just a noticeable bump.

A couple years ago I did a CC305 cam on a LT1 I build, ported heads, exhaust. Car makes over 400 horsepower and is great on the street with a 6 speed. I imagine the same cam with some aftermarket heads, and a miniram or stealthram intake would make close to the same horsepower. My LT1 is 11:1 compression, but I can get away with that due to the reverse cooling. The SBC probably keep it 10.5:1 or under.

Unfortunately, the factory heads and intake are poor flowing on these cars. To 'wake them up' you really need to do heads, intake, cam, exhaust or if keeping the engine stock a small turbo or supercharger.

Is this the issue you are fighting with the current setup?

Re: Where should I start and with what?
The question too is what you're willing to do tuning-wise.
Something like a miniram or stealth ram is going tk require significant retuning as theyre difficult to get just right.
Otherwise probably get a high flow TPI set up.
