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?

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.

Looking at the builders YouTube channel………it appears he’s no stranger to the street, street/strip SBM Mopar builds.

I agree with RAMM in that I’d be way more concerned with differences related to testing procedures and weather variables than whatever small power differences are the results of the slight change to the short block configuration. I agree, and feel like I’d be able to extrapolate some useful...

Tough crowd.

The age old question……. What’s the difference in power between manifolds and headers. And the age old answer is…….. “it depends”. I look at it this way……. In terms of the typical ohv v8……The more hp/ci your build makes with headers…….. the higher the % of loss you’ll see with manifolds. 20 or...

I’m sure for the guys that run a lot of 1/8 mile, they might have a good handle on what’s a decent slip value for 660’. Most combos will have way way more slip at 660’ compared to the full 1320’. Myself, I have no useful data for converter slip at the 660’.
