Mid-high 12's my guess.

Those heads suck.

 

yeah I know. im on a tight budget right now and thats what I got

 

I also agree, probably mid 12's to high 11's with the juice.

 

Thanks for the detailed info you provided, it makes running the computer dyno easy without having to look up anything. As mentioned earlier, you will see significant gains in the future if you upgrade your heads.

 

I had a very similar engine in a 79 Malibu a few years back, 355, 11.3:1, camel back heads, 3500 stall, .525 Magnum cam, roller rockers, victor Jr intake, 3.42 posi, 750 double pump holley, car weight was 3400 with me in it. and it went 11.80's on motor and 10.60 on 250 shot.
