I thought I would start a new thread with the interest from board members.I just got the intake I bought.This is a diff version from any I have driven.Randy Williams built this one for the Pontiac racer and collector Bill Blair.It is a lot like one version I had dyno tested for him.The originals had a flat plenum floor,this has the V plenum.It has a lot more meat in the intake runners where it mates to the heads.Going to get it scanned and look into have some casted.Tom

This version has the 61-64 water pattern.IF I do them they will have 65 and up!Tom

[Gary H]

Good looking piece. Very cool project!

[Drag Star Le Mans]

Pontiac started the tunnel ram craze with a killer factory intake. Very cool!!!

[RA462]

Very very cool piece. I would love to have one myself that fits 65 and up..

[Don Keefe]

Keep me posted on this project. I will be happy to put a news item in the magazine about it.

Only you could answer this Tom, but is their anyway to have a single manifold that would accept either water pattern? I ask this because if possible, it would satisfy every ones need with a single casting. I also assume you are considering having them 3D-printed in aluminum rather than a sand casting. It would be interesting to see what the cost factor would be with all the new 3D technology exploding. I have 2 3D metal capable shops withing 20 miles of my house. I would be happy to help if I can. Feel free to PM me if I can help.

Don, you could start a column in your mag, titled, What’s Tom up to, today!
The cool things he gets his fingers into, are usually off the scale! Even if it was something he started on and decided not to complete, it would be very worthy print to ALL of us that get your magazine, which includes me! You missed a nice get together this year at Great Bend! Jeff Bolton


I got to talk to Arnie’s awesome daughter, Rhonda for a while, at Great Bend, Arnie’s doing well, for all the crap he’s been on through in the last year

[GT182]

I had a long talk with Arnie at a PY show a few years ago. Very nice to talk to and very appreciative of all of us keeping Pontiac alive with our cars.

I dont want to go that road,IF I loose my mind and decide to do this it will be 65 up water pattern.If someone wants to run it on early heads they would need to remove the water Xover and use a early one along with getting the port work to match the ports.I will have the intake made with RA IV size ports and location with enough material to make bigger.Tom

[mgarblik]

Well, that would certainly work for me as I have not really worked with the early heads anyway. Are you thinking sand casting or some sort of 3D printed finished product? Or have you not moved to that point yet?

What would be the best late model heads for my 62 GP 421 if no 127 heads are used. What heads did you use. Thanks for all the info.

If your shortblock is already built , you might need to consider cam lift and which type/size of valve reliefs your pistons have.
You could run big valve heads up to a certain point of valve lift with small valve reliefs in the 421 style pistons.

Tom is saying he used big valve heads 1971 #96 , with 96cc chambers (if stock).
If he did a full fresh build -- he probably used new pistons with proper larger valve relief size.

[421mike]

Hi, I have one which I am not going to use, it's brand new and yours for the original price of $2500.00 dollars if you are interested. PM me if interested. Mike

[tom s]

Guys,John had a few late style bottoms and the foundry cast up a few tops for him so there are some avail.Im sure John will get on here and confirm what the price will be on what im pretty sure will be the last of them.Tom

[tom s]

For more info you can call John at his office.949 975 9965.Tom

Tom, out of curiosity, what is the final count on how many bathtubs were made?
