Built to spray a little, but decided to go N/A. Car is now finished just in time for the bad weather. We will run this engine for one season before selling it and doing a full N/A build.

Almost a clone to mine....why is mine such a turd by comparison? Hey Jim, could you share some cam/valvetrain specs on your build? PM if you want. No offense to any others, but this an impressive build for the power output. I am sure I am 100 hp less with almost the same combo and more compression.

Why do you think yours is a turd??? I certainly don't.

Dean has the cam card so I'll post the #s on Monday. From memory, I think we ended up with 1.8 intake and 1.7 exhaust Jesels. 278in/294ex 113 installed 109. Peak hp was 8200 on the best pulls.

We had a good flowing 15* head to start with, then had Matt at MBE work em' over some. They went just over 400cfm @.800 on 2 different benches. Matt also did the bulk of the work on the 420, then we had Gabby open it up when we switched to the 110mm SV-1 from the 1.590 x 1.750 4150 Willey's carb.

The dyno work was on Precision Automotive's inertia dyno. Hopefully it's not too happy. From some other engines that spin on that pump, it seems pretty close. I believe Emilio's engine was pulled on it too. Norman (Precision owner) and my brother tuned about 80hp from start to finish and we actually freshened the engine (including rods) during the dyno sessions, we made so many pulls.

The car is finished so we're going to do some in-car tuning, then make some rent day shots as soon as we get a chance.

The proof will be in the timeslip once we get everything squared away.
