BP 428CJ Stroker - 465 Cubes

[mbrunson427]

Today was the day that the 428 Stroker for my Galaxie was dyno'd. I don't get any credit for the engine, this one was all Blair. I had a good idea of what I wanted for the '62 and Blair guided me into a recipe that he thought would make me happy....originally this engine was going to be topped with a 3x2 carb setup and C0AE-D heads but here's where we got to:

By the way, a personal thanks to Blair for being so patient with me, answering all my questions, and teaching me a ton along the way.

Blue line shows long tube dyno headers, red line is a test with Tri-Y headers (because I'll be running Tri-Y's in the car)

Very impressive

[WConley]

That is a beautiful thing.  Iron heads 

Congrats to you and Blair.  That '62 is going to be such a great sleeper.  Torque to infinity and beyond!

Solid rollers on a hydraulic roller cam? I'm wondering if that's a typo or something actually done? I know it's been discussed at length on the forum before, but wondering the reason for doing it, if it was done.

Nice numbers, and with iron heads and an RPM intake. For a stock looking car, that nasty sounding idle is gonna be a dead give away!

Doug, not a typo. This is something that he swayed me towards. I had originally sent him down a set of hydraulic rollers.

That '62 is going to be fantastic with that motor.  Really nice to see the Tri-Y headers also on the dyno, thats a great data point.  Any additional details on the cam specs?

Beautiful !! sounds great ! It's hard to believe it's a cast iron head with those numbers , dang that's impressive

Very nice, can you share compression ratio and spring pressures, ( if they are not proprietary)?

Sounds strong.  Where was it dyno'ed at?  Joe-JDC

Sorry, should have included compression. 10.17:1. Intended to run on pump gas. Spring pressures I don't have a clue.

Any additional details on the cam specs?

I don't know much more than that, judging by the way it idles, I think Blair pulled a fast one on me and gave it some more duration The car doesn't have power brakes so vacuum was less of a concern.

That's a nice bit of skepticism there Joe (if I'm picking up on it right). Go back and study Blair's 400 cube EMC entry, and then extrapolate out a 65 cubic inch add and some other variations (like intake).....After all, nobody in the contest doubted the validity of that dyno.

[frnkeore]

Very, very nice!

What carb are you going to run on it?

[Joe-JDC]

Simple question, just curious where your dyno is located.  If it is a secret, then I can live with that.  BTW, I was there at the EMC.  Joe-JDC

I note that you show a pair of the old, cast iron Ford tri-Y's, in your Project thread. Are those the ones that you will use in the car, or the ones pictured on the dyno?

It might be very interesting to see what they(cast iron) would do to the engine on the dyno.

Jay and Barry have both done back to back tests with the cast manifolds. 

[frnkeore]

Does anyone have a link to the tests or, know the approx date?

I had a set, that I got with my LR. They were the first thing that went to the scrape pile ('68/'69 era) but, only because of how much they weighed. I always wondered how well they worked.
