better check the heads for clearance.


When you give cam details, dont just give the lift. Need to post the LSA, duration, duration @.050, etc.

Never mentioned compression ratio either.

Have a 96 gmc 4x4 pickup, took out v-6 and put in 89 350 with carburator, anyone know correct timing, and plug gap? Answer would be much appreciated.

he wasnt talking to you. He was talking to the guy that created his own thread and asked a question.

I would suggest you do the same instead of hijacking someone elses. And to answer your question, just go to advance and get a set of Ac Delco plugs for that year engine and set the gap to .045. Timing around 32-34 Total.

Re: Vortec engine, cam, carb power question

So you have an all stock 95 Suburban engine with 96-99 Vortec heads?

I would estimate 300hp with 906 heads. If you have the stock 95 heads, 230hp.

Also, its normal for the other rockers to be loose. Just carry on the way you've been doing. Turn it back to #1 TDC and see if they're still loose. I bet they're not.
