Good evening guys. I don't really have any buddies into racing so I gotta show it off here lol. This has been quite a few years in the making. It's going in a stripped, caged 73 Duster with an 8" convertor worked over by A1, built 727, 4.88 gear and a 28" tire. I'll be running all 1/8 mile.

.040 over 360
3.58 stroke
Icon pistons
Scat crank
Scat rods
Trickflow 190 heads
Comp solid roller
1 7/8" headers (that need coated lol)
Victor 340 intake
HPI 750 E85 carb

Nice looking piece. How much compression? Are you going to dyno it or let the times speak? Should be a very fun ride...Congrats :thumbsup:

Thanks! It's 14.02:1. I'd like to dyno just to see but I'm not sure I'll get to it this year.
 
Looks nice, but all that with just a 750?
 
Is that the forged Scat crank and H-beam rods?
Scat 9000 and I beams. Kinda came down to what I had. The difficulties I had sourcing a few parts made me say "you know what back in early pro stock this was a factory crank factory rod deal" . May be a death sentence but I'm told they'll live. We'll see. I haven't scaled the car but I can't see it being over 2900 or so with me in it and that's a heavy guess.

Well they say that 750 will flow 830. I lack the experience to say for sure. I do have an HP950 which I believe is also said to flow in the 830-850 range. I've got some help with this one so we should be ok.
 
Seeing it's a E85 carb, are you going to try and run that with the 14 to 1? Or is methanol your chosen fuel?
 
I'm not even close to a expert on alternative fuels, but even with a big duration cam and the aluminum heads, my advice would be to be real cautious with the timing at first and just sneak up on it as the engine allows.

agreed. He also must have a dome piston, which can also make for being careful. That is lots of squeeze for E85, but I have heard of 15 to 1 stuff not detonating with E85, so who knows.
 
.627/.638 276/281@.050 106 lsa. Just got a new phone. Cam card is on the old one.

Thats more duration than the cam in my Indy headed 434, peak power on the dyno was 6750 rpm’s. If your heads will support it, that thing should be a screamer up top.

Nice build, keep us updated.
 
You’ll be fine at 14:1 on e85. We’ve run 30psi on 10:1 and that engine liked all the timing. It has great detonation resistance and great latent heat of vaporization. When it’s in the car or on the dyno do timing sweeps and find out what it likes. The chamber on the trick flow head is supposed to be pretty efficient. Also, holy carb spacer Batman!

Lol the carb spacer may have been just for the photo shoot lol. I'll talk with the carb builder before we run that thing. I've been hearing about guys running up to 400 on the bottle and lots of boost without pulling timing.

This is uncharted territory for me. Yep Icon 743 pistons with an 11.2 cc dome. We may learn a thing or two. Probably things we already know but I'm game.

I just updated my comment to say that lol. Sometimes I write in a way that doesn't divulge much info. Then I read it again and think man that ain't very personable or informative.
Did you have to do any machine work to the pistions to get them to work with the trickflow heads? I am running a stock bore, stock stroke 360 magnum in my 91 dakota sport, that has the trickflow heads. I am right at 11.1 compression now. I am wanting to raise the compression and switch to E85 for my dakota race truck. Sounds like the icon pistons will work for me. I look forward to hearing how your engine runs. Sounds like it will run hard. What ET are you hoping to run with it?

No machine work needed. The chambers are similar to a magnum chamber. We are looking to run in the 6's.
