Found This Interesting Page On The Hamtramck Registry

[shittyslant6]

So I was bored yesterday and I went looking on the Hamtramck registry and stumbled on this page:The 1970 Hamtramck Registry - Vintage Racing - People Behind The Scenes: Ed Poplawski Page . A lot of you have probably seen this page already,but for those who have not, here is a 288 with TWIN DOMINATORS. that revs to 10,000RPM!!!
HOLY ****!!
And nowadays most people are scared of running engines past 6,500....

Back in the 70 and 80's pretty much every M/P engine ran up to 10-12 thousand...287ci... boy I loved that sound

 

[33IMP]

Tiny engines, 10,000rpm, and 60 lb flywheels.

 

[shittyslant6]

so I now have decided to stop looking for a 318-360-340 and am now looking at 273's

I feel like 10k Is the correct and only acceptable rpm level for little motors

Hard to imagine the rotating mass at 10K. Makes me cringe thinking of that flywheel coming thru the floor boards like a buzz saw.

More like a hand grenade

Well, people do evolve over time. Thank God.

if i was in the car, i don't think i'd be able to tell the difference between it coming apart at 6500 or 10,000

You'd definitely know when it chops your legs off.

In 1977 two sets of gear head friends of mine were at a party. During one exchange, one friend from one group said that his 383 in his 69 Road Runner could do 10,000 rpm with no damage. Another friend from the other group threw the BS flag. So we all headed outside. The Road Runner was fired up and the BS flag waver had to sit shotgun in order to observe the tach. He pulled his legs up on the seat because he knew the flywheel would come apart and make him a double amputee. The driver took the engine up to 10,000 rpms and side-stepped the clutch. The sound of a high winding big block was replaced by the high pitched scream of rear tires leaving two 2 inch piles of shredded rubber on the street.

Thats what scatter shields and Kevlar blankets are for.

And I am wondering what heads he used and what they flowed at 10 k.

 

[brian6pac]

Big bore, big valves, short stroke. 4.07 bore 2.75 stroke = 286 cu in.

F1 engine at 19,000 RPM

See if you can find videos on the 50cc three and four cylinder Japanese grand prix bikes. I think some of them redlined at 25k rpm and idled at 13k rpm.

About 10 years ago I was looking at some at a bike show, if I remember it was 50cc 13 speed gear box and yeah 25000 RPM

Iron heads ported by Ron's in the US..titanium valves,retainers and locks.some of the very first sheet alum intakes.C M/P index 9.00 to 9.99 most could run under the index.

I have a bunch of original dyno sheets from one of those 288 cid small block motors.

It was an idea. But I don’t know if it got raced.

My Chrysler internal correspondence between Tom Hoover, Bob Torozzi, and others seemed to say it was an idea that didn’t work.

Browsing through many runs by Bob Tarozzi’s Phoenix Engineering, looks like all around 520-540 or so peak HP. BTW, SVI= Ted Sphear.

This run had rpm “issues” it seems by the comments

 

[brian6pac]

A buddy of mine back in the 80's had a 277cu in small block Chevy tunnel ram in a 76 Camaro with a Nash 5 speed 5.38 rear went to the U.S. Nationals and did good, not a win but it was a fun weekend. If I remember it went 11,000rpm

 

[autoxcuda]

Here’s some objectives of the same 288” motor(s) Bob Tarozzi was given to evaluate:

DRE = Bud Elkins ported/prepped

but what "iron heads" and what did they flow?

they would have to flow well over 350cfm to take a motor over 8k.

i think I have flow sheets for the DRE 79811 and 77789. They were tested on different motor CID combos.

This stuff I have reference to are one off stuff not available for public sale…. W-2-1/2, W-3, NASCAR heads, Petty heads, “good castings”, etc. I’m sure some are special castings, and some are welded up heavily modified.

These “288” heads may had have the huge rectangular intakes like the Bob Glidden SB heads had. Not sure
The 70 race Trans Am heads had wider rectangular intakes too.
