Felpro 1077, 32 on 114 octane. and 12lb of boost.

What rod lenth is that, and is it the same as a Merc 900 or sterling 1050. Trying to stay with the conventional head stuff.

6.635 is a good rod length for that combo

those work great for us!

That with a good Isky tool room gold stripe spring eliminates the bullsh1t 50 hour service.

These 557s that make 1100HP went 178 hours since i built them with the big lifters and Isky springs.And they got murdered too.

the 1077 is the mls gasket i have had good luck with them, are they leaking water or are you blowing them and if so where

Finish on the block has to be to the specs that Fel-Pro want for that gasket.It says it on the case that they come in.

you are right just got to hope he had that right hell i like that gasket better then the cometic

I don't like a sq or over sq motors.the thrust angle and the big slug your trying to sling..

Remember back when the Nascar guys were destroking there motors making more power.

Also why do you think Sterling is running that cube, they have people spending $$$.I bet the experimented on a few costumers I would think they figured it by now whats the best combo, again there looking at max hp in a race application and usually have a higher RPM peek hp .I would think The bigger the ci the lower the RPM.
