almost done
 

ok only thing left. cam!!!! i have ben pondering this question for a long time. what cam to get.

what i have

289 bock 30 over
Holley 3190 4bbl 650cfm carb
edelbrock performer 289 intake
302 ported heads (unknown years)
Hooker super comp headers
with 2 1\2 flowmaster exhaust.
bolted to a beefed up c4
with 3.55's
engine runs very well
i was thinking of rejetting the carb but didnt want to do that untill cam. what cam should i get
i have a 1500 or 2200 stall. my tach is crummy so not sure.

motor pulls to 4000 then drops. i drive in the 2500-4000 range usually. if i can get a cam past 4000 for that 90 plus freeway driving cool but if not i love that zero-sixty...:0)

any ideas what i should get. somewhat conserned about vavle to piston clearnace. also im told to replace the timing chain when you do a cam swap from stock. why is this needed and what is a durable chain? or should i go gears??

any ideas? thanks..

The timing chain should be replaced simply because it wears out. Might as well do it when you swap the cam since you're in there already. Same goes for lifters. A dual roller chain is the way to go; less stretching problems than a single row chain. I wouldn't install gears if I was you. They are noisy, expensive and are not that important unless you're planning to run at high rev's all the time.
