OP Mancini cover, Allstar cover look like the same thing:

I wonder what Blueprint Engines is using for covers/pans for their crate engines?

Is that area of the cover different for a Magnum, and/or that piece of the pan gasket for a Magnum?

There’s mention of the SM’s being bought bare, and being assembled with better parts……… but I wonder if the seats were re-cut and blended. And if not……… would that be worth anything on a build like that? The one set of cnc’d SBM SM’s I had here had a valve job I didn’t love. Cnc’d pretty much...

Pretty substantial difference …….. especially at that power level. If you built the SM combo, what are you going to buy with the $700 you saved to get back the missing 40tq/30hp? I agree it would be interesting to see how a set of “prepped/blended” SM’s would stack up.

If the stroke is now 3.54”, then they added .160” stroke. If the pistons are 1.485” C/H, and the rod is 6.70”, the pistons should be down the hole .025”(in an uncut block) 1.770”(half stroke) 1.485” 6.70” ———— 9.955” .025” deck ———— 9.980”

Frankly, I can’t believe this is a question. It’s an easy thing to correct for zero dollars spent. Why wouldn’t you want it right?

Published specs for the PAC 1903: [email protected] [email protected] 391lbs/in rate This is the same spring as the TFS-16893

Need to know what heads are being used, and the available installed height.

At $2800 + parts and shipping……….. in 2013 dollars……. I wonder how many takers there were for that?

All your Speedmaster “needs” are still only a phone call……..or click……away. Just not Summit or Jegs phone numbers………for the time being.

When your just a bystander, you can’t really complain if someone else’s dyno testing doesn’t follow the priorities you’d have if it was your test. That being said, “if it were me”……. And I was going to orchestrate a SBM head shootout test……..I’d want to use a short block and induction/exhaust...

Are you familiar with the dyno service he uses? Looks like a nice enough set up.
