Pic of one

I just got done doing one,copied from a rare Pontiac SD tunnel ram intake.We 3D scanned it,3D printed a plastic to confirm fitment.Needed a little computer work to fix some thing.After that we had to have it converted to solid works to make the patterns.Hope you get a good pattern maker and good fou...

I was never able to get 3in as quite as I wanted,went back to 2.5 and made a huge diff.FWIW,Tom

In 1963 pontiac 421SD 859 intake was a dual plane and ran very well.Also in 63 they released the "Bathtub" tunnel ram intake.Tom

I have been running 2-4s since 1962,on a pontiac but no matter if a dual plane,single plane or tunnel ram they drive great on the front venturies of the rear carbs.I only went solid when racing the car.A set of factory med riser holleys would have been perfect.KISS seems to always work out.FWIW,Tom

I would set them up progressive like the factory did.IMO,WAY more EZ to drive.Tom

Comp 875s are .842?Tom

Engine Supply in Santa Ana.He used to do Joe Shermans machine work.Tom

I saw a Victor modded to go on a ehead on the 61-63 4 cyc.They just cut and welded to get rid of the drivers side.Tom

68 firebird.Tom

Looks like with the pumping compression it should run on 91?Tom

The advantage of Splashzone is you mix the 2 parts wet.I usually get a 5 gal bucket of water and do a golfball size of the 2 equal parts.I put my hand under water and work it until it becomes the green color.Remember it is a marine epoxy made to setup underwater.It is very EZ to form and smooth with...

I don’t think Comp advertised who made their lifters over the years.You can look up Ron Shaver,the shop is in SoCal.Tom

The lifter body looks just like the previous Shaver hyd rollers lifters.Tom

FYI,when talking about size of carbs.Carter had a 930 CFM 3bbl carb in 1963 for the Super Speedway Pontiac cars.They had a special intake to allow the "trapdoor"blade to open.I have owned a few of them over the years.FWIW,Tom
