Post my 289 with 302 what cam what hp????

i have a 289 that has been rebuilt 3yrs ago it runs good but i wanna go faster i have some stock 302 heads that have been ported 3 angle valve job and have been milled to approx.61cc and the have trick flow valve springs good to .542lift i want to put a cam in with the heads and not sure which one , i heard the isky 280 cam was good but was wondering if it was the right choice and what else should i change while messing the valvetrain

my future plans is a 331 stroker kit either on my 289 block or a '88 302 block and would like to just about transfer everything over easily so basically would that cam be good on my stroker too

and how many horses would i be pushing with heads and cam?
thanx

Joe sherman, who just won the smallblock shoot out. swears by the isky 280 mega cam. He built a 302 for hot rod magazine useing a 302 crank, 289 rods, 289 hipo heads (no thermactor bump in the exhaust) and flattop pistons, he got just over 400 horses from the 302 useing just that cam. another bennefit is that it is about half the price of its competitors if you buy it from PAW ( www.pawinc.com )

I just bought the same cam for my mustang, do not get it from PAW it is backordered and they do not know when they will be getting any in, i got mine right from Isky directly http://www.iskycams.com/ they have the cam and lifter kit, 67stang you should have kept the 289 heads they would have been perfect for the cam because of more compression (55cc),Also you are going to need a good stall if its a automatic and gears, intake to run that cam.

thanks for all the feedback
what stall do you prefer i have a 9inch rearend with 3.25s and a rebuilt c4 and a edelbrock performer intake do you think i should use a different manilfold

and i do have 289 heads that have been ported and have 1.94 1.60 valves i think but i know they are bigger than stock are these better than the heads above
thanx again

67stang,
Go with the 289 heads, take the trick flow springs and put them on the 289 heads these heads will offer the compression ratio that cam needs, also a 2500 stall and a 4:11 axle ratio put a 650cfm carb on it, that intake has to go you need something in the 2500-6800 range like a torker II. This is a good combination to kick some Chevy Butt, "I could not resist". <img src="graemlins/evil.gif" border="0" alt="[evil]" />

Hey there stang take it easy on us Chevy's. LOL. I have a Chevelle and I have the ISKY cams. Only they have a 505 lift. But they work awesome and I highly recommend them. Had for a while with no problems.
Good Luck
