There's a 93 coupe running 6's in the 1/8th mi running a 306 with AFR 205s, I will see if I can get more info on the car, he runs at one of the local tracks...
The tq'er manifold is a tad outdated. You'll find that a Weiand Stealth would be a much better choice for that combination. Should run real nice. A middle 11 sec combo.short throw said:306 roller
10 to 1 CR
Roush 200's as cast
1 3/4 LT's to 3" Prochamber
Torker intake with 650DP
So who has 205cc heads and RACED it? There is one example that was raced on a track.Jay Allen said:In 1991 I had a 100% stock block. I flycut the pistons in the block with a dremel in the driveway. I used TFS Street Heats that were 205cc (2.02 X 1.60). At 600" lift they went 305/210 cfm. I used a Wolverine WG 1087 with 1.7's. 222/232 542/567 w/1.7's 112 LSA with a 107 IC. I had 10:1 compression. 1 3/4 Motorsport J-302 Headers. 3" exhaust. A TFS Truck intake that utilized dual 54mm TB's off of a 460 EFI truck. The first Pro-M EVER made and it was 24# injectors. A FMS 110lph pump (the biggest that there was). A stock T5. 100% stock suspension plus Lakewood slapper bars. 4.10 gears. 26 X 10 slicks. Nothing, absolutely NOTHING by todays terms. The car weighed 3280 with me in it. It was the ONLY car my wife and I owned. Thus, we drive it EVERYWHERE! AC, PS, PW, CD player, it was all there. I went 11.471 at 117.1! By the math that is over 400 RWHP! Guess where I shifted and it went the quickest? 5800 RPM and it crossed at 6300 RPM. I had a computer (Crane Interceptor prototype that was given to me by Doug & Mike Wallace) that allowed me to shift higher. I did. I shifted at 7000 RPM because I could. I went 12.30's right off the bat after I had went 11.60's with a stock computer. Thus, I began to short shift. The faster and faster I went as I short shifted. I ended up at 5800 RPM. Now I do not feel that the WG1087 was even near optimum, but back then there was only 3 cams available and *custom* was a Taboo word. The same combination today would be very close to a 10 sec timeslip because of the parts available.
205cc S/H's at 5800 RPM with a 3" stroke at 5800 RPM. Go figure.......
Chuck98GT said:The objective of my combo is to keep velocity up and to get it moving early int the RPM band. On the dyno my 306 makes 300+ RWTQ from 2800-5100 and peaks at 346 RWTQ with the converter locked through an AOD. HP drops off after 5500. Last winter with a 5600 pill in the shift light the car ran a 11.41 @ 116 on motor.
When I daily drove the car, it would get lugged at 1200 RPM in 3rd or 4th gear and never buck. I figure most OST cams are designed for 5 speed cars that can lauch off the rev limiter or be manually held in a lower gear to keep the revs up if need be. Which is why I went with one of Ed's cams.
Math?Jay Allen said:So who has 205cc heads and RACED it? There is one example that was raced on a track.
Daily driver that my WIFE drove.
At 3280lbs (by the math)(more theory) that is:
11.471 @ 3280 = 429.5 RWHP
117.1 mph @ 3280 = 407.2 RWHP
anyhoo, your opinions very welcome, and appreciated.NewOldStockMatt said:but, i believe comparitivly they are not quite the same as a ~200cc head on a 300" motor..... but i could be wrong...
Is that a joke?Jay Allen said:Forget the smoke screen. Where are the middle 11 second, 165cc heads, 3200+ lbs cars?
I'd really like to know how it runs. Take it to the track or if you already have, post the times, please.N8Miller said:Guys,
while i am not totally up on this thread, all i can say is that Jay Allen really knows what he is talking about. he made a cam that is "smaller" than my comp cams xe274, but runs SO much better with my "bigger" vic jr head setup.
when i saw the specs, i was a bit worried how the car would perform, but now that rick got it together and the MAF is rebuilt, the car runs AMAZING!
thanks again, Jay
I can take a stock headed 302, port it only (no valves), use a medium duration cam (say 218/224), put a nice intake and exhaust system on it and make the same power. I know cause I've done it. Putting another motor just like it for my brother.Jay Allen said:You want to be irrelevant. So will I. How about the DOHC Cobra? Seeings how everytime I bring it up YOU side step it. 281cid. 300cfm heads. Same *Port Volume* as a 200cc Canfield (TFS S/H or Z304). Passes emmissions. Idles baby smooth. Lots of power everywhere. Guess that engine is theoretical as well huh? Guess the Ford engineers are wrong too. Let's do this.
