For what you are planning I would recommend a crate motor from GM, they have a 12/12 warranty with their motors.
You could not build one that cheap, you can get a 383 or a 385

its all opinion man......

how much can you put up with is the question???

in my driver i had a 600+ lift in a sbc 850 holley, 261 castings ported etcetc, with dual 3" flowmasters.......yup it was loud.....but it was also very very fast.

when i build a motor for my nova its ganna be a sbc again...big carb, big heads, big cam, big exaust, then afterwards worry about how bad it is on gas milage.

yes, its very fast...I think youd be very happy with the 280 magnum..he's running a holley dual plane, 680 street avenger carb, dart Iron eagles, comp 280 magnum and a stock one wheel peel 10 bolt...can you say traction problems? if he ever gets it hooked up it should run 7.90's to 8.0's in the 1/8 mile easy...he plans on mini tubbing it and going with a 9" whenever he gets the cash...HTH

Um, the stock ones

Any 23 degree non-vortec head will work just fine with everthing else on your truck.

yes, you can use the stock heads..or if the cash i available there are many aftermarket heads that will work, dart, edelbrock, canfield, AFR, pro action, to just name a few...also the vortec heads will also work but youll have to buy a specific intake just for the vortec heads. I think you can buy them from GM for like 550$ a pair assembled, or scoggin dicky has packages available thats really hard to beat..HTH


here is scoggin dickey's web site if your interseted

Really you should wait till you have all your parts together befor yopu select a cam.
You need to know your:
cubic inch
intake
carb
compression
heads/valve size
headers(primarie size)
tranny type
converter rating
rear gear
rear tire diameter
weight of the car
also you expectations and needs and what your willing to put u with to get it.
Basically changing cams is tuning the torque curve of your motor,put the curve in the wrong spot or have parts that aren't capable of keeping up with the flo needs you may endup with a discouraging motor.
Nothing worse than over camming,especially if the car sounds bad but can't back it up.

Wink

like 78 monte said get your parts together and what i would do is call Isky. I'm a believer in Isky cams and their tech's. Just tell them what you have and what you are using it for and they will tell what works best. Bud.
