7/16 rocker studs Yes my engine builder decking it to o.o so I can get 11.1.1 compression heads are AFR210cc and are 65cc not really sure on the Quench what would u recommend? I'm not using a comp cam I'm using a Howards Hyd Roller Cam. 3500stall converter 1.6 rocker or intake and 1.5 on exhaust which make it to a 636/600 I believe i'm not really sure i'm new to this... But this is the cam i'm going with right below ....wyrmrider wrote:couple of questions just saw your latest post after I typed this so some revisions
3/8 rocker studs??
what's your deck height with your chosen pistons, please say 0.0 (and adjust piston to get compression)
your "quench" would be your gasket thickness- the closer the better
on your cam choice
did Comp say to squeeze the lobe centers-comp recommends for 9:1 and 3000 stall and use 110 LC and 106 ICL
but no mention of 383
my take is that is a conservative (but not very conservative) cam
236 @50 can be done with 280 @.006 not needing 288 still with .360 lobe lift and mid 150's @200
or
same seat timing @.006 288 can have more "intensity" to get you over 240@.050 and over 160 @200 and over .360 lobe lift
you could have .620 at the valve with 1.7 rockers
If you already have the comp cam 1.7 rockers would get you around .600 lift on the intake
so what converter??? OK I see you said 3500 that really helps (and tranny cooler)
If daily driver I'd go with the shorter duration higher lift solution no matter what seat duration you can live with
8 degrees is a lot to leave on the table
