Ok, that’s fine

 

ive been suggested that 227 232 612 595 113+4 would be the smallest id want to go with AFR 210 heads?

 

I like those durations,splits & lifts! alot for the AFR 210s and your goals/combo. A FAST 90/92 with 90/92 TB would be worth 15-25 through
your whole curve 3000-7000 RPM. I would go 115*+3* BUT and its a big BUT LOL, Im over 50 and favor stealth & low speed manners.
112+3,113+4 all splitting hairs.

The AFR cathedrals because of their outstanding flow & E/I relationship need less exhaust split and/or overlap to provide excellent results
along with much better low speed manners and driveability with small to medium cams.
Just dont choke it down with the LS6 Intake any longer than financially necessary.
My .02.
Good Luck

 

yep, probably will go fast 92 combo, i think these cam specs with 112+3 would be the one!!

 

would you mill the heads with this cam?

 

That is a great compliment to AFR 210 heads. Great midrange.

 

have gone with 227 232 612 595 113+4
next question should i mill the AFR heads? and if so what to?

 

What gas are you running? Do you know your current CR?

 

no current CR as engine is being built for a conversion to a 70's street car, fuel will be pump gas 95 or 98 octane

 

11.5 compression. 60cc chambers depending on your deck height. .041 head gaskets. Send it

 

With that static CR and the suggested cam, should the dynamic CR allow using gas even lower than the 95-98 octane he predicts using?
I hope that doesn't sound too naïve...

 

Usually when I see 95 or 98 I presume it is outside the us. Often foreign 98 is about like our 93.

 

98 octane is the aussie version of USA 93 octane.

 

Gotcha. Thanks to you and Darth!

 

correct, im form NZ so our octane same as australia

 

So im nearly all sorted,just waiting on parts to arrive, set up will be
LS1
AFR 210 heads
fast LSX with fast 92mm intake
1 3/4 headers
4.11 diff
manual
227 232 612 595 113 cam
YELLA TERRA 1.7 roller rockers
any suggestions for injector size?
cheers

 

42 lb/hr will be plenty
