Hi Billa,
If you're still doing desktop dyno, would you mind doing a comparison?
I have a 1965 coupe with a 1971 LT1 shortblock & edelbrock RPM heads
with hooker sidepipe headers & a performer RPM intake with a 750 CFM HP
Holley carb. I have the AFR 195 street emilinators to install & I was wondering
what the difference is? Thanks, Jules

If you are still doing dyno numbers here is another one for you.
434 sbc
10.5 compression
afr 210 competition heads 2.08 & 1.6 valves
int ex
.200 - 147 120
.300 - 206 166
.400 - 257 214
.500 - 290 225
.600 - 308 235
.650 - 311 237
.700 - 312 240
4.155 bore 4 inch stroke 5.850 rod length
super victor intake-port matched with a holley hp 950 carb.
1.75" long tube header, no cats, flowmaster muffler
lsa 112 solid roller with 1.65 ratio rocker arms
intake - duration-243.7 lobe lift-.37965 valve opens 14.4 btdc closes-49.4 abdc
exh. - duration-249.7 lobe lift-.38087 opens 60.8 bbdc 8.9 atdc
It needs a bigger cam, feels like it peaks around 5400 rpm. would prefer 5900-6100 pk hp.
Thanks for your time

Billla,
Thanks for offering to do this. I am in the process of finalizing my build plans and would really appreciate this tool. Would you mind doing two versions, with different heads? I am trying to see the impact of a choice here. Here is my build:
Version 1:
Big Block Chevy
6500-7000 Redline
4.290 Bore
4.25 Stroke
6.385 Rod
491 ci, I believe
10.4:1 CR
3946074 Aluminum Head
Flow at this cam's lift: 307 Int / 187 Exh
295 cc intake port
2.18 / 1.88 valves
Crane 134691 Cam
290/300 Adv. Dur 110 LSA .580/.600 lift
@ .050: 256/266
Here is the cam card:
http://www.cranecams.com/?show=brows...tType=camshaft
Rocker 1.7:1
Headers 2" / 3.5"
3" Dual exhaust with Ultraflow mufflers
RPM Air Gap - Rectangle port
Holley 850 CFM DP
cold air induction
Version 2:
All same, except the head:
Brodix Race Rite - Rect
intake 294 cc
flow: 332/217
valve: 2.25 / 1.88
If it is easy, I would also be interested to see if the AFR 305 is worth the extra time and Money:
AFR 305 - non-CNC
intake 305 cc
flow: 357 / 276
valve: 2.25 / 1.88
I really appreciate your generosity and willingness to share your time and knowlege.
