2 1/2 years and 3 pages of posts in the "Proven Builds" section about an engine which hasn't even been run yet.

Previous shop 2.5 years+ no progress..... current shop 4 months and ready to dyno...... imagine that.

Just pointing out that this is "Proven Builds" not "Projected Builds".  To some people there must be no difference. confused

The proof is on the way


I imagine some pretty impressive proof numbers at that!!!!

Ended up with 1100hp at 6800 and 920 to at 5800

On C16 with a quick fuel 1450 with a out of the box intake port matched only.

It's on a tight Stuska dyno too, not a superflo like most everybody uses.

Should certainly haul the mail. Sweet build.
I am sure there is a bit left on the table with the OTB (port matched) single four intake manifold.
Did you flow test the head with the intake in place?

More pics?

Cheers!!

No we didn't flow with the intake. Just clay radius in the intake with a 4.625 bore.

I want to upgrade to EFI in the future, the C460 cast manifolds have some very poor distribution

Too bad BBF cast manifold choices are limited to one (C460). BBC guys have many many choices these days.
A Sniper BBF would be nice for C460.

You didn't pull it higher than 6800 or that was where it made peak or...?

You could use the adapter plates and use A460 intakes. That new Eliminator intake would look good on there.
