Pretty much the only difference between this motor and yours is that this one has a mechanical roller cam and yours is hyduaulic. They also used a Victor JR. With those two things in mind, I think you will be around 475-500 hp. I wuold be a little carefull with 11.2:1 compression if you are thinking about running pump gas. It might work just fine, but it may not. That is a pretty big gamble when you are only probably talking about loosing around 10-15 peak hp by going to 10.8:1.

cam specs

Malc here is my cam specs,

Malc also my total lift on the cam will be .640 intake and exhaust with my 1.6 rockers......

And Adam (firestone) the motor is already built and has been running for two years minus the new AFR heads that I am waiting for and the Air Gap intake. No detonation and runs strong. I always run premuim fuel. And 110 VP Race Gas is in my tank most of the summer.

Right now I am running a set of 1967 Camel Hump 2.02's and a Torker II intake. With the new heads and intake I should have a solid small block....

Today I am installing my new YANK 3800 stall converter and having my turbo 350 110% re worked.... Currently have a 3200 custom stall and stock Turbo 350

Here is how it sounds now........ Click Here

And here is another sound clip...... Click Here

Thanks guys......

Dave

KO I am still in the dark with the actuall flow numbers. I originally ordered AFR's 195 comp current casting. Then found out that they where coming out with new Comp 195's so I switched my order to the new castings. So here I am waiting patiently....

My AFR rep told me that the new 195 comp castings will flow as good as their current 210 race heads. And I could expect no less than 25 increased HP from the new castings over the current 195 comps.....

As good as my car runs now with the old Camel Hump 2.02's. I just can not wait to test drive the new AFR heads with air gap intake and my new YANK converter....

Right now I shift around 5900 to 6100. AFR said stud girdles are recommended for my new setup... And he also said welcome to the 7000 plus RPM range....

Thats great. Being that you have the new AFR's, I think you will probably be in the 500-525 hp range. I based be previous estimate on the street ported old casting heads. Have you looked into the AFR hydra rev kit? I had a motor wtih a hyd roller cam that floated the valves around 6500 RPM. Not long after floating them a couple of times, one lifter broke. I would think peak power should be around 6500 RPM on your motor.

Here are the peak flow numbers and some other info...

AFR's New Eliminator 23 Degree SBC Head Raising the Bar in Performance

•Light weight 8mm valves, valve springs, retainer and lock components

•Light weight parts reduce valve float, increase reliability and performance gains of 75 HP with hydraulic roller cams at 6500 RPM

•Whopping 10% increase in flow at all valve lifts. Our 195cc flows 300 CFM at .550 lift and the 210cc flows 310 CFM at .600 lift!!

•180 and 195cc available now! 210cc in 60 days and our all new 220 and 227 (325+ CFM) shortly there after

•Most efficient, highest flowing 23 degree head available, our street head out flows our competitions race head.

•No other true bolt on 23 degree head comes close!!

•State-of-the-art work cell for reduced lead times.

Called AFR, they said the email I got was a couple weeks early and contained a typo... the 195 flows 300 CFM at .600 not .550 lift. The flow numbers they gave me are for the Eliminator "Competition Package" heads.

Eliminator 195
Lift INT EXH
.200 140 115
.300 202 165
.400 248 200
.500 280 217
.550 292 N/A yet
.600 300 225

Eliminator 210
Lift INT EXH
.200 147 117
.300 206 166
.400 257 202
.500 290 220
.550 302 N/A yet
.600 310 230
.700 315 236
