First, here is my motors' specs.
502 honed .004 0ver to 4.47 bore
SRP 17cc dome 10.2 to 1 Pistons
zero deck
Clay Smith solid flat tappet 304 Adv. 258 at .050 .615 lift on a 108 LSA installed on a 105.25 I.C.
Jesel shaft rockers 1.8 intake and 1.7 exhaust
AFR 315 CNC heads 121 cc chambers
Holley Strip Dominator Intake
950 HP carb
Eagle +.250 H-beam rods with the L19 rod bolts
GM forged crank, internal balance and knife edged
Compression ratio came right in at 10 to 1. I wanted to go a little higher but was talked out of it.
I am going off of memory here as I will pick up the motor Monday and the dyno sheets, but the best pull with my carb was 605 at 6300rpm and 586 lb ft at 4900 I believe although the curve was really flat with 500 lbs as low as 2500 I believe. Just for the hell of it we threw a 1050 Dominator on it and it picked up 15 and 15. One interesting thing was when he tried his standard dyno 800 cfm holley that he knows runs good and has been blueprinted, it equalled the best we pulled out of my carb so he thinks the 950 hp is just an 830 or so given the 850 baseplate and 750 main body. His dyno is by his own admission very conservative but very accurate in repeatability. All pulls were made at 200 degree oil temps and 180 water temps. I bought a Victor Junior but realized quickly it would not fit so I sent it back without running it although I would have liked to. The back measured the same as the Strip Dominator but was too high in the front. He was very complimentary of the AFR heads and thinks it is the best out of the box head going right now and he has done many big blocks. He said this engine should be plenty to scare me with for a long time. I can't say enough about how great this man was to deal with and how impressive his track record and his facility are. If anyone needs work in the New York Tri-state area I highly recommend this guy. His name is Bill Carlquist at Carlquist Competition Engines in Oakville CT. I will post some charts and some exhaust testing results we did when I get the sheets. Joe (Flareside) this was for you buddy. Bill.

Question for you, why did you go with a tapped cam? You are giving a bunch of number there.

I believe someone here with the same heads and similar compression on a 468 he made upwards of 600 HP.

Still great numbers for a streetable 502, have fun with it smile.gif

Yanniz, just didn't want to deal with the hassle of a solid roller, yet anyway. Somewhere down the road I may do it. This motor is also going in a 3100 pound Corvette so my goal was 600 anyway since even with my upgraded rear end components I don't want to go breaking things. It will probably see a couple trips to the strip a year, more for mph than E.T. I do want to chassis dyno it to see what numbers it will pull at the wheels though. And thanks to everyone on this site for the help and for telling me about Bill Carlquist. Thanks, Bill.

Carlquist is the man. He did my heads smile.gif i think in the spring ill be bringing my motor down to him to dyno it...what did he charge for dyno time if you dont mind my asking?

Bill,

do you know what jet sizes and power valves you have in the 950. Nice numbers good luck! Curious about the fuel curve. Thanks

Rich

What heads are you running.......

Orange Juiced, I don't have my itemized bill yet but I will let you know what he charged me for the dyno time.
Rich, the jets are 82's all around and we never changed the power valve but I am not sure what comes in a 950HP but it is pretty interesting that he thought there was no way it is a 950 cfm carb. I know that subject was hashed around here before. Wish I had gone with the 1000HP now.
Bluebauer, I am running the cnc ported 315cc AFR's.

Looks like good power to me & I`m glad to see someone using a Claysmith cam besides me. graemlins/hurray.gif

Jim

Jim, the engine builder hadn't seen a Clay Smith before either but was real impressed with the quality and it survived break in O.K. What cam are you running?

Excellent results. Cylinder heads being the gateway to hp, those AFR's deliver the goods. Sooo, how long until you run your Vette at the drags?

Thomas

Thomas, I probably won't get the car to the strip until the spring. I hope to get it on a chassis dyno in the next month or so. Bill.

Bill I~m running a 292 adv. 240 @.05 .485 lift sold Clay. Seems like a real nice quality cam. The first thing I noticed when I took it out of the box was that the lobes had the edges deburred , seems like less of a chance to flake off a little something & start a faliure.
