The funny thing is there is more left.If the Cam was a 242/246 on 112+4 you would gain a good amount of torque and alittle more up top.

I'm not going to question your experience or knowledge on that point. I'm sure it's true, however a big part of selecting the cam I went with was to maintain driveability between 1200-1500 rpm's. I think we achieved that. The car is docile enough when 'lugging it' that I can take my wife to dinner in it and leave the keys with the valet. No way was I able to do that with my last build. That was a stock bottom end with these heads untouched and a 224/228 112 + 2. I would think that a 112 LSA would move the torque curve higher and make it narrower, or would setting that cam 2 more degrees advanced bring it back down, i.e. +4 vs. +2?

Thanks Bob, in the end it was well worth all the extra effort. It's really weird how it drives at low speed and rpm, but when you step on it, it makes small children and women cry . You're going to love it. Hurry up, I'm anxious to see what your results will be.

That motor is FAT with torque! Yeah, you gotta be light on the pedal around town because it gets snotty real fast.

Hearing the awesome results you got, and the fat torque curve you are working with has my mouth watering for my engine to be built. I can't wait !

its all in the right combo for the job thats for sure. i have thought about putting the cam back to 0=113 as its so hard to hookup. i think less Tq and maybe some more in the upper RRRRs would make it faster at least on the street. as for the track i need the Tq to get 3900LBs movin LOL

No doubt. I think the next mod is going to be a beefier, maybe Stage 4 M6, with a Stage 4 3.73 rear. I'm only @ 3150lbs, unless I sit my fat azz in there. Now 1st and 2nd are like steel wheels on ice.

LOL i would pray for 3100 me 250 in the car now doing some weight mods and bigs littles got us to 3590 but wow 3100 thats awesome. 10s would ba a breeze.
i know what you sayin buddie and i were talkin about that to day at work, back after it got built the street tires werent safe LOL. third gear it would do a little dance. hell 2 mo ago i had it open headered and with the mostly bald 275-50-15 DRs it would spinn from a 3rd gear roll. all this power under the curve might be getting out of hand ya know.

wow nice results man...Tony is the man, he ported my fast for me and id come back and work with him anytime. Ive also been tuned at ECS so i know you went in the right direction with your shop at least....Doug and the rest of the guys do a great job and run a professional shop, id recommend them to anyone. Looks like a little port work goes a long way on those 205's.

Well, it's more like 3150, but who cares, lol. The FRC's are pretty light, and I did some other things, but it's hard to take weight off. With the rear tires being so far back that also limits traction off the line, but from a roll it runs pretty well.
