compression with higher dosage of nitro
wideopen231:
After this weekend with A/Fuel TA/D it is going to get higher on both. Running 15.5:1 with 95% is just too xxxx much fun.

Love it, Intake Valves kissing the pistons in every hole...

no intake kissing but exhaust makes out pretty good. Remember the heads are fat head style with lot smaller chamber than std Hemi. Easier to get high compression. Owner said Prock spent about 6 hours one day profiling cams and pistons to get even more compression. Two hours chatting off and on with Procl might be coolest part of weekend.

At least if they just kissing they are little ways away from getting- -----d up.LOl Had quite a few setups where they marked top of pistons a tiny bit.Polished them out and sent them back again.

100% positive we are running that high with 94.3 t0 94.8 in tank. What amazed me was if run lean it will drop cylinders.nothing else happens.We have to roll some bearing in her,but thats about 15 minutes.
