can I use a lt1 intake on a stock 350 tpi without changing the cam or heads and still get a gain in performance out of it or would i be better off using the edelbrock base and high flow runners ?

 

The LT1 intake will only fit if you convert it to a standard SBC bolt pattern, drill a distributor hole, add a hold down clamp and boss, and add coolant ports because the LT1 does not have a coolant neck for the upper radiator hose. You will also need a remote thermostat and a few other things.

 

I have the remachined intake with the distributor hole l98 bolt pattern and remote t stat

 

Ehhhh, I'm not sure you'd see much of a gain. You'll gain alittle on the top end, but I'm afraid that the loss in torque you'll have will not be offset by the minimal (small cam) gain on the topend.

At least put like a ZZ4, or Hot Cam in it. The ZZ4 cams can be had on Ebay for like $130.

Although you might have to have the valve guides machined and springs/studs. You can do the Studs yourself with a Mr Gasket kit ($30). Springs 981 ~ $50. And machine shop labor ~ $40 for machining guides.

I think then you would have a fun little combo.

Then you will have made your heads the limiting factor in hp, not your cam/intake. Next purchase would be a good set of heads to let that 350 LT1 breath.

 

My car feels a lot more responsve now. I think that it's a great swap. There's a lot more info here
