Dyno time.

Cam is real close to the one I’m running. I like it!!!

 

[DonSSDD]

I jjust used experiance Don but should have added `1,00 rpm to go with the heads and intake.

I figured that Dr. Don.

Dan, some details. The engine is only about 11.7 comp, the cam is nothing out of this world as we knew the head was limited, it turned out to be a pretty good combo.

Hopefully this info can help a fellow racer as we have Fords and Mopars to send packing!!

The firing order is same as LS Chevy 18726543, 1.7 rocker ratio, BAM BB1 DLC pin solid rollers. The guys at DIAMOND, BULLET and BAM were very helpful and all are highly recommended

What are the valve sizes and bore and stroke?

 

[chevytaylor]

Not sure on valve size Dan, probs as big as would fit in the Edelbrock head, bore is 4.5" and stroke is 4.25".

 

[Ishiftem]

Best I could do taking pictures. Interested to know what what it calculated for header specs vs what you tried. Scary how close the program estimates hp.

 

[La Hot Rods]

What is the difference in the the collector between the two, I know there some help in both.

 

[BSL409]

These heads have had the same Bossman program as yours Keith. The McQuillen intake must be a big factor as well.

A step up to the Z stuff will be on the cards for sure Don, not in this particular car though. The plan is to enjoy this thing for a while street/strip running easy 10.00's (that's my tech cut off) in our IHRA and ANDRA DYO 10.99-8.50 Super Sedan SS/A national championships, then it'll eventually become an iron block 409 street cruiser again. If I can save my pennies and save my dimes Dick Mackenzie will be getting a phone call

1/4 Mile ET & MPH By Weight & HP
Enter the Weight and HP for ET and MPH, Then Press 'Enter' Key
MPH = 234 * (HP / Weight) ^ .3333
ET = 1353 / MPH
Weight Horsepower ET =
9.979
MPH =
135.578
