Watched your videos of assembly of this one and 428. They turned out nice!
-
Nice Brent where the cam specs in the ballpark of a stock High rise cam. I dont know if the specs are confidential.
-
What are factory cam specs?
-
Nice build!
Do you think the factory 2x4 and carbs would yield more power?
-
That's a bit better than the Ford advertised 425hp ;D
We have a dyno sheet on a high riser that was intended as a 100% stock rebuild, made 530hp with the 2x4 intake.
-
Which cam Brunson?
-

Absolutely.
Or Jay's intake adapter with a big fat single plane.

I'll look for you this weekend. If I remember right it was a comp custom grind trying to mimick the factory cam. Not quite an exact match but close.
-
Which cam was this engine running?
-
Well, dynod my Nhra stocker blueprinted high riser. Untouched ports in the heads and intake support power well in into the 600s.....solid flat tappet cam with .524 lift.

Any specs on that one as an NHRA stocker vs a Ford delivered version?

Filled block, thin rings, bbc rod journals, 20+ more duration, better valve springs, valve job, .013+ stroke, compression is just a tad over 15, 3 step headers......
-
Certainly makes sense. I bet that is a stout machine!
Almost enough compression to run on diesel fuel ;)
-
Who makes rings for a 4.24 bore?? I thought the closest was a .017 over which would be a 4.25 bore.

Cool to see the old HiRiser data.
Not sure how you'd count the T-Bolt out of Dearborn Steel Tubing, but the 64 LWG Lightweight Galaxie was a real assembly line 427 HiRiser car.
(all 100 of em)
Cast iron exhaust manifolds like a real civilized car & dual exhaust too.
The factory cam was identical to the C3AZ-K 427-8v cam, 324-324 244-244 114.5 LSA .525 .525 gross lift.
The only difference for the HiRiser C4AE-B cam was a much closer LSA=106.
Totally streetable Sunoco 260 grocery getter except maybe in Michigan winters back then.
Gonkulates right around 500hp with the factory iron exhaust in a nominal build.
