I am about 2/3 the way done on my swap. I am getting rid of the performer intake for a Holley Street Dom. and the heads are being replaced w/ 67 vett. heads the 64cc 2.02 double hump heads (they are true humps because they have no bolt holes). The heads also have screw in studs, guide plates, aftermarket valves, and a minor valve job.

I am wondering what kinda time do you think I will see tonight? I have to get the cars finished and I planned on going test and tune tonight at Muncie.

Thanks for all the help!!!

Also the casting # is 462 (I think) and the valve springs are double spring after market ones. You can tell the heads have been machined for larger springs.

30 year old heads with 30 year old technology. How much did you invest in the heads? Unless you got a smoking deal, it would have been better to buy some Dart heads for the same price or less and got a much better casting.

Although there's nothing really wrong with those heads, they are very outdated to the aftermarket selections available now. 30 years ago they were the only real performance option. Today they're only good for people who want to build a "numbers matching" car.

Without the accessory bolt holes in the heads, you're going to have a hard time mounting any accessories to the engine. Alternator, powersteering, AC etc.

 

Best run of the night after the swap looked like this.

R/T .749
60' 2.192
330 5.876
1/8 8.849
Mph 82.77
1000 11.411
1/4 13.568
Mph 104.60

I think the 12s are there w/ some tunning. I dont know if it timing or carb. My buddy is going to take his holley back so I need to find another one. I think I need to jet this one but dont know anything about holleys. I am thinking about electric conversion kit for the water pump from summit.

The car bogged off the line almost dieing and then broke traction on my best run. I took it up to 7200 rpm at one point and she coulda took more. I was shifting on my best run at 6300 and 6500 rpm.

I traded off a headliner, small 3pc spoiler, my old 4" scoop and stock hood. In return I got these heads and a set of Comp Engien. Subframe connectors. I dont think I got hurt.
