Re: cam swap need some advice

You need some compression for that cam, and it will be a PITA on the street. If you have the compression, and the exhaust side cleaned up a little on the heads it should work out great. The vortec...

Re: ENGINE COMBO SUGGESTIONS/TIMING QUESTION...

You will have to get a different intake, but if it's worth it depends on price. It will really wake up that engine though.

If the heater lines are cooler then the radiator hoses, then bypass the diverter valve. If the lines are still cooler then it's the heater core.

That's the power range for that cam. To raise the power range, you will need a stiffer cam. Your heads will support the power as long as you have enough compression.

Re: Got the trans am pics of engine.

The casting code will show what the block was to begin with. To find out if it's a 383 you have to measure the stroke. Drop the pan, and see if it's 3.48 or 3.75 inchhes.

A larger cam bleeds off cylinder pressure, allowing you to run more compression. Check your plugs, and try premium with octane boost.... I bet if you do both it will run a lot better.
