+1^ what Tom said.

What your dyno chart does not show is the run-up to 4800 rpm. I suspect the TQ curve down there will be quite impressive also. High torque at low engine speeds provides an exceptional driving experience. Like Tom suggested, it will be quite exciting in the lower gears.

That's good stuff. If Blair dyno tuned your engine I doubt he put a Turkey Pan and small filter on it before he adjusted the Holley. So, the customizing that he did might not match to your setup as you have it installed in your ERA. Not a big deal by any means, just something to tuck in the back of your mind. That's half the fun.

Your displacement is actually 445" if your specs you listed are correct. My KC built, Pond block side-oiler is a true 482" and it's 4.25" x 4.25".

I bet that was a typo on his part. I actually do have the 4.125" stroker crank in my block, along with a 4.155" bore. Of course that opens up the debate as to whether a 4.125" crank revs faster than a 4.250" crank, all things being equal. Personally, I have always believed that the shorter stroke results in a shockingly improved rev factor.

I always thought that too Patrick, until my 4.25” stroke 428 that Keith Craft built. Not sure if it was their balancing work or just the light weight of the car, but it revs crazy fast and very smooth, very much like the Ford 3V modular motors (which are also under square).

The stroke length number itself has zero, zilch, nada to do with how an engine accelerates. The weight of the rotating assembly, the camshaft, compression ratio, and a few other variables have everything to do with how an engine accelerates.

Does anybody have experience of Prestige Motorsports for an FE turnkey build?
I’m way late to this thread. Congrats on a great motor from a great builder.

Apologies, and yes a typo, it should be 4.25. Well spotted!
