off topic question

[68chevelle]

iv been getting the same idea as crapmaster. im starting to doubt twin89s honesty.

[Twin89s]

no dyno as the engine is in the garage as far as how valid it is I only have the #'s from desktop dyno...

If you wish I can provide you all the info on my combo.
But the heads are ported and polished
the cam is aggressive
etc...

other than that why do I have to prove shit to someone named crapmaster? Many boards know of my combo many boards have seen my combo in person. Hell I bought the combo from many boards....

wow i leave for 2 hours and now there's dogs jumping off bridges and crapmasters talking about the shits. lol

[Twin89s]

here...

1991 Corvette L98 Shortblock with windage tray
1967 Chevy 461 heads (57cc) 2.02/1.64 valve ported polished (about 180cc's)
Lunati bracket master II cam (0012 for those wondering)
Solid lifters
hedmenn super comp headers
Mufflex Y pipe
Edelbrock performer RPM intake manifold
Holley Double Pumper 750cfm (81 jet front 78 jet rear)
Compressions is roughly 10.2:1 compression
Scorpion 1.7 roller rockers

and yes I have taken into account this is a flat tappet cam that I am putting into a roller block. I already have the pushrods lifters etc...
do the desktop dyno on it yourself then talk shit!

[68chevelle]

i would like the info on your combo. because i just guessed and what i cam up with was far less than the power you were talking about.

[Twin89s]

posted already


yes I know the headers on the engine are not super comps those are my shorty hedmenns I am selling pretty soon here. The Super Comps are ordered.

[68chevelle]

umm 1 question. why are you running solid lifters on a cam that is a hydralic cam?

[Twin89s]

its a hydraulic flat tappet cam. Instead of running the hydraulic flat tappet I am running solid flat tappet lifters. it gives a bit more power.

[68chevelle]

ok i could see that maybe. but the max power i get is still only 400.

[Twin89s]

Take into account for the increased lift and increased air flow.
Also figure in for the super comp long tube headers. The exhaust is basically free flow. I havent ordered it yet but I am putting on a 4 inch cat back with the new motor. the 461's are ported and polished. Lift I believe should be like .550-.570

[68chevelle]

so you dont know how to figure out the lift when you change rockes do you? oh and where did you get the 1.7 rockers anyway?

[68chevelle]

oh and is that the intake your running in that pic?

[Twin89s]

yeah its a dual plane edelbrock performer RPM
Scorpion makes 1.7 roller rockers for SBC thats where I got them ordered them through a local speed shop

[4onFloor]

what lifters did you use in that roller block? not doubting just asking

[Twin89s]

they are lunati lifters they were like 90 bux.
