4 years later I finally get to drive it!!! Runs awesome on my 462 with the bath tub intake. Its definitely a handful in a 2700 lb car w a muncie 4 speed.

I imagine a lot of us wish we would have or could have grabbed one of them.
Is anyone building a 65 GTO prototype test car with 2x4 induction ?

Looks fantastic! Would love to see what others have done with their bathtubs. Mine is still on the workbench waiting for the machine shop to finish with my block. Hopefully I will have a running engine with a bathtub by the summer.

I’m sure if John got enough orders he would order more castings.I think he had to get 10 at a time.Tom

The demand for the 61-64 heads was not that great.Im sure if you had a late style head on your your 62 as I do you could have a intake in short order.Tom

Do you have any suggestions where to go for a supplier?

[tom s]

These units were custom built.They were only sold by the maker.Innova Engineering in Santa Ana CA is the maker.John Cogger is a member on this site.He is making and selling the Pontiac underhood LS blower systems being shown on this site.Over the years there have been 3 reproductions on the Bathtub intakes.There was one for sale on this site,not sure if its still avail.Tom

The early style intake had lesser demand and I think they only made 1 batch run of them on this particular latest project .
And that was it.
Those have all been sold now . And no more planned

The 65-up style , I think they made 2 batch runs.
And no plans to do anymore of those either.

I run a set of 980s on my 63 421 Lemans with a Johnson-Zajack repo Bathtub,om my 62 GP I run 96 heads on a 63 HO block with the mule Randy Williams intake.It was originally a early style design.After we confirmed the fit we 3D scanned it and made a plastic intake to confirm the scan.I then sent it to Jim Robertson in TX and he converted it to a late style as Randy designed the casting to be used for early or late.Jim had to raise the ports .250 to mate with the late ports and also converted the water X over.Got it back,3D scanned it and made a plastic intake to confirm the fit.I then put it on my 62 with a pair of 62-63 Pontaic SD NASCAR 750 Carter AFBs.There are lots of late Dport heads that would work depending on CI.Good luck with your project.Tom

Does anyone know of a 421 SD block that is serviceable. Had one that turned out to be unserviceable. Ready to buy immediately.

[tom s]

Why a SD block?Just get a nice 65 or later 421 or 428 block so you can use a block mounted starter.Buying a 421 SD block is just a complete waste of money.Or just get a good 400 block and use a aftermarket 4in stroke 3in main crank in it.Tom

Thanks Tom for the help

FYI,I have a late style intake if anyone needs one.$2500 plus shipping.Tom
