I probably have close to $6K in that motor.... too bad it's been sitting there for the last 7 years and will probably sit for another 5....

alright. i got the heads for about 300$ invested. im kinda excited to see how they perform.

yeah that's what I paid for mine initially but unfortunately they were o-ringed??? hmmmmmmmm wonder why???[sm=nxsmile.gif]so when I put them on they leaked coolant/warped and had to have them decked and o-ring surface removed...decking and new gaskets and new valvesprings and set up on them to match my cam and 400.00 more invested they were good to go[:@].....but they are lightly ported, and new valve job with larger valves abd new seals and perform well!!

so mjr, we have the same cam AND heads on/in our motors? jeebus

mjr46

so you enjoy your heads than mj? nice, im real content with my set-up now. Gonna hit up the dyno real soon. btw, anyone wanna buy some underdrive pullies?

well they are on my 66....and I threw the build together on a budget and wanted aluminum heads but they weren't in the budget and I didn't want stock heads so I found the next best thing from a friend...and the car with the stock 74 302 in it with only a 4 barrel and headers ran 15.4 @ 88 mph.....so I rebuilt the bottom end had a Nos crane fireball cam sitting around .500/.500 lift and found these c9oe heads and roller rockers and rpm air gap, and with a t-5 in it and 3.50 gears on street tires I got it to run a 13.31 @ 104...so yeah I'm pleased with it since I never really put a lot of thought into the parts combo/build
