Len,WAY back in 1963 the factory found the bathtub tunnel ram needed a pair of 750s on the 421SD.My 366 RA V liked the 625s on a 2-4 tunnel ram,made HP to just under 7K.FWIW,Tom

Can you still buy a new Gutsram? I sent an email to the Wensler site a month ago and haven’t gotten a response.

Okay tested Gutsram with with two ed 650s left timing at 36 degrees same as with victor race demon combo picked up 18 hp but air fuels were on the rich side and did not have time to wait for metering rods and jets leaned it out some with what I had but was still below 12.50's . I bumped the timing to 38 and gained 10 or 11 more hp and was still climbing at 6500. I reached my goal of 600 hp so pulled motor off dyno and stuffed it in the gasser, as there was a pontiac show in NH I wanted to make . The victor race demon combo was really dialed in and if I had dialed in the Gutsram combo better I think the Gains would have been greater. Will continue dialing it in on street and strip.

Default Intake Manifold Dimensions

Not trying to Hi-Jack this Thread at all.....

What we need to do is to create a Thread with Internal Intake Manifold Dimensions for the various Intake Manifolds that are now available. That's what's most important after all.

- Port Length
- Port Inlet Dimensions
- Port Outlet Dimensions
- Plenum Dimensions
- Angle of the Port (Port Angularity) in relation to the "Intake-to-Head" Flange Surface
