[QUOTE=Dan A. Macal;1315866]I have never ran any power adders on any of my stuff EVER. my 66 F 85 ran 9.60`s leaving from a dead idle 373 rear gear and I drove it to work several times. NO electronics, trans brake-NOTHING. When you get done with class racing, maybe you can graduate up to bracket racing. and if you think it`s easier than class racing....show up at the world footbrake challenge in Bristol TN in July. I bet you can`t get past 2 rounds. Everything I ever ever raced, I`ve won in. I just went through all my trophies moving. 296 total wins. 98 with 1 car. Ya know what.....you wouldn`t make it past 2nd round at a normal saturday night bracket race. I like class racing.....atleast until I found out you do it.[/QUOTE



Got it, what did you say that thing weighed? You could be right about the bracket racing, either I do very good or very bad. I don't claim to be a bracket racer, but I do drive and race 9 and 8 sec full weight small tire NA street cars, some with production GM engines. The NA race cars are faster

Can you post some pictures of this "66"

 

See what i mean!

 

Its one thing when I get into it with Dan or Duh, they have actually done something, Dan a hair more than Duh, but you have done absolutely nothing, and that car of yours is a disgrace. Thats why I rarely comment on anything you would post.

 

Love you too!

 

Dan,
Is there any numbers for torque below 4700 rpm?
What a beast!!!

 

I can answer that. Bill didn’t make any pulls lower than that for whatever reason. I agree that It would’ve been nice to see what it made down around 4000 or so.

 

The reason Bill didn't pull it lower is because if a person was to utilize the BT engine to its full potential it would never even see 4700 RPM on a run down the track, plus starting the pull higher would be easier on the mains.

 

But how would you know that unless you pulled it down that far. You throw out the first and last couple of numbers anyway.
If you think peak tq occurred at 4500 you’re a bigger Dyno idiot than I thought. Unless you pull it beyond the initial high points you really don’t know everything you need to.

 

Pretty sure you'd want the converter to flash around 5200 RPM with that combination.

 

That would make an absolute wicked jet boat engine with the right pump... Lots O Grunt down low.

 

Looking to do the same thing for my '69 442. What was the final cost, ballpark? Thanks.

 

A lot, a whole lot.

 

Thats pretty accurate I'd say.

Much appreciated. An that's the perfect answer, beother.

if you have serious money, pm me. I’ll sell it.

 

Did this race happen yet? 😁

 

This is a fantastic Olds engine. If only there were solid main 403 blocks. Dan's engine proves out what I was hoping for as far as potential of the hated 403. Is there a "light" version of Dan's 478 that started as a 403? I already have a nice 403 in my car, but looking to an upgrade, defiantly not to the extent Dan has done. Good heads, stroker crank, roller cam... I know the crank is a huge piece of the puzzle, but is there a way to keep the block in one piece? Care to share? Dan, Bill, Mark???
TIA

 

the only way to do it is a 1 piece billet girdle. Not a J&S bolt together

 

 

I can’t wait for it

 

you actually think a dry sump 463 inch 11.3 to one making 1.49 per cube is nice?

With a solid roller, .776” lift

 

Thanks Dan, figured that.
I guess I need to ask Bill about the billet piece $$$ for another.
Keep up the good work.
Edit: We do have two 5 axis CNC and 1 three axis CNC milling centers at work now.

 

hey joe, ask mark about the 403 I did I got all the parts from mark. 9-6-1 hydraulic roller on 91 pump gas 470/494 then mark recalibrated his dyno he’ll have to tell you the rest. Affordable build

 

Merry Christmas Dan and Thanks. I'll get a hold of Mark.
At some time we need to have to get together for a beer or three. I may move to Florida at some point. State of ILL is just that. ILL. Im looking north of you though. We need to talk...

 

I just moved to Georgia due to a job offer. I miss Florida terribly but do like it here.
thinks to do in Illannoy- leave

 

People complain about Illinois blahhhhh . I got 4 drag strips within 100 miles appx . From where I live ., Silver linings lol.

 

Bernard, I posted a link to a but load of pics of the little Lycoming I did in the major projects and builds section.
Edit: Moved to the clubhouse?

 

yup. You and I discussed it and think peak torque is probably 3800-4000 and more towards 660 tq.

 

I know that this is an old post, but I am trying to find out where I can get ahold of one of the stroker cranks described. It was mentioned that Mark made them but I am trying to find out how I can get in contact for my 403 build.
