Dave did you ever put the main stud girdle on? I'm trying to decide if i need one for the 340 stroker build. yellow

Yes. It is installed. I'm using a 71 360 block filled above the soft plugs and using ARP studs.

Not sure what your referring to. My new build is on the stand waiting for the Dyno and it will not make 750. I will be happy with 650.

I used the 360-1's fully ported to 230+cc range and max flow was 330@700 and 800. Mid lift numbers are way up as well. Dwayne welder did all the work. They look real nice. Will see how they perform.

What are your engine HP numbers and what does your combo run? What have you done to your heads.

Dwayne welder got the exhaust flow better as well. 210 to 144@700. Smaller exhaust valve too 1.625 vs the old 1.650. The whole package should work much better.

Our builds are similar, heads and intake are the same. I'm only 11.2-1 though. my cam is 263/271 @ .050., .741/.738", 4.09" bore and 4.125" stroke for 434". Mine should be finished and on the dyno next month. I'm not planning on posting any numbers though, to many arm chair experts.
