Is this a right choice?

I am planing to make a carb swap. I bought 350 engine from pickup K3500, 1993.

I plan to buy holley 3310 carb 750cfm and holley strip dominator intake (300-64 part nr.). will this combo work great? i will also put compcam 8-302-8 in 350.

No that combo will not work great.

Besides missing a lot of information that carb is way to huge for that engine and cam.

I will run holley 300-64 intake with holley 80670 carb.
My next question is what will happen if i put in my compcam 8-302-8 (which is produced for TBI engines - info from their homepage)??? I think it must run ok with no problems.

By the way 305TBI has left my Camaro

i agree the combo should work fine.

but,...you may have to address some other issues like adapting the fuel line, fuel pressure regulator, trannsmission cable and bracket if auto, etc.

Re: Is this a right choice?

After cleaning engine I find casting number and could search info about it.
Must be roller cam:
''10243880 = 95-00 Vortec truck, 2- or 4-bolt mains, roller cam, one-piece rear seal. ''

So, the final choice was Edelbrock performes RPM + Holley Street Avenger 670cfm.
At this moment engine is in his place and have been fired up. Sounds nice. Need to finish with wires and I am ready to hit the road.

Re: Is this a right choice?

glad to hear its coming together for you. have you used a timing light on it yet? might be the video, but it sounded a little advanced or the battery was weak while cranking? take your time tuning the carb and ignition, it will run much better.
