Guys, I didn't want to post till I was done. She is home and ready for the dyno in a couple weeks. I drove about 60 miles yesterday to get all the bugs out. I will post up the numbers on here when I get them.

Anyway, my 383 had a couple bad lifters one morning, so I yanked the heads to see what was up. While waiting I got the go faster bug and ordered a new 418 with more cam and big bore AFR 230 heads.

Anyone interested in my 383, I will post in the 4 sale area soon. Only 14k miles and a proven mid ten second motor.

Way to go Pitt! I've been wondering why I haven't heard from you,,,,,you've been busy! Looking forward to seeing some good numbers from it!

Yeah Jim, hitting it every weekend. So good to finish up.

Also still trying to get truck tranny straightened. Haven't been able to make a full pass yet. It did shift to second one time, then bounced off the limiter 3 times before going into 3rd. Ran a 7.2 @ 96 with a lousy sixty foot and 96 degree degree air intake. That was my best mph in cold air before, so she is running great.

By the way...the new 418 is running 35mph in sixth on the old 383 tune with no bucking. Must be pretty close already.

I hate to see another 383 go ..

Best of luck with the new 418 what are the goals?

CTD

I had supposedly ported AFR 230's on my 416, best was 518 RW. That was with an ugly camshaft.

pit-man

I know right...I hope to just get lower than my old 10.6

I am expecting a little less than 518, as this isn't a max build. This thing is the smoothest 650 lift cam I have heard. Sounds almost stock to me after the 383 cam.

It is a Pete Incaudo cam again.

CTD

Are you telling spec's or top super secret With AFR heads I went from the ugly 17* of overlap to 10* with LSK .650 lobes. Made the same power with day & night manner improvement & much more tuner friendly. After I switched the heads the LSK lobes broke two valve springs last summer. So I've Swapped out the cam again, 5* of overlap & slightly less lift ...... Back to the dyno this spring hoping for a minimal change in power, trying to achieve the perfect street manners with confidence in the valve train.

pit-man

Don't ya hate the retune when ya change cams. PITA

No top secret...650/610, 235/245 on a 114 lsa. Heads are stock 230 Big Bore AFR, CR is 11:1

I hope it is near 500 rw

ZZOOM06

You should be right around 525/500 with those heads and cam Bob!
When are you going to dyno tune it?

pit-man

Prob wait 2 weeks to get a few more miles on it. Rings sealed right away, no smoke at all.

CTD

That is close to the cam I just took out, mine was closer to .650 on the exhaust @ 243*. 10* of overlap vs your 12*.

I'm a Fast 102 ported, screwed up by the same guy that supposedly ported my AFR 230's. I also have a NW 102 TB, AR 1 7/8's with a SW 3" out the back & cats. That combo did 518rw & about 476ftlbs if I remember.

Your 500rw should be a reasonable target.....easily.

I'm so happy to hear of the progress, Pitt! I hope this motor gives you all you want and more!

pit-man

Thanks Pete. I hope to enjoy it as much as you do in your red rocket

Looking forward to your track results, hoping to have my new motor in this weekend finally getting back to the track, knocking the rust off and giving you some motivation for low 10s!
