1963 Grand Prix

Day by day I said in the past.
Try everyday to get some task project going or done.
Some days I relax and plan out In my mind.
 
You did a great job with that head porting.
But talk about valve shrouding! :rolleyes:
It looks like Pontiac created a cave for those valves to reside in.
I see you were generous with the bowl hog. No choice here.

Everything I learned from Chad, Darin Morgan, Richard Katterjohn a SD455 Super Stock Pontiac Racer with a 1982 Trans Am, Scott Foxwell, Brent Miller in Pennsylvania, Michael Miroux, & many more the Pontiac Chambers should not work as well as they do stock.
I did careful deburr the sharp edges like Grumpy taught me here.
Polished with Medium grit 120 cross buffs from Abrasive standards.
Cross buffed the exhaust ports so carbon would not stick easy.
Intake ports finished with 80 grit sanding rolls like Grumpy taught.
I wanted to do the Chad Burr finish.
Only 1 friend in Texas can sort of replicate.
Chad has video out he shows how he does it with a Carbide but in A Makita Electric die grinder.
Electric is out choice 1st Porting now.
What I used too but a Milwaukee M12 Cordless I bought just for, 1st to try out suceed with.
It's pure Art Magic how Chad Spuer does it.
The way his human brain is wired to his Hands Porting !

They work A-ok.
Takes exactly same 1970 RAIV Ignition spec initial and mechanical timing to perform make power.
Once set, back in March 2021, Haven't touched the Magneto since 1000 miles later.
Just concentrate Tuning the Holley Double pumper 4-bbl.
Actually unshrouded 1968 up all Pontiac V8.
What you think is right dry flow is often 180 backwards wrong for wet flow.
No flow bench, no dye to use, used Grumpy Know how to.

All Cylinder Head Porting and intake Porting was done outside on my car trailer in 2020 Summer heat.
Worked at it 5 days non stop.
1 day it was 24 hours non stop.
Engine assembly under my attached Lean to shed.
Engine installed on dirt and grass layed down 4'x8'x3/4" inch plywood sheets worked liked concrete !
Also worked in Snow storms outside 2021 tuning away.
 
Options are Real Limited now for Brand New Aftermarket Parts Mike.
All Edelbrock Aluminum intakes are unavailable period for a Pontiac V8.
Quality is very bad reported by Chevrolet guys on much .
Huge No can have indefinitely now.
Including all New Dart blocks.
Same in Pontiac V8 world.
You either have $100,000k And find the right guy.
Or build stock with Cheep China parrs it will blow up.
Or do what I did.
Port away.
 
Ok, I have some questions. Are all aftermarket cams etched? I’ve been wondering if my sbc motor that I know was rebuilt by the last owner - upgraded the cam at that time. I don’t want to take it apart unless I have good reason to believe info could be there.
