Chryslers in OPC...

I found this one of Roddy Foreman at Kankakee, unfortunately it is a poor quality picture.
I think the motor is a 5 cylinder 150; a MOD 110 class setup.

here is a shot of Roddy's formula 100 Kaos boat. Tracy Hawkins used this same hull in sst 120 and even won the nationals with it.

Didn't really happen but do you think Chrysler had that idea in mind?
If not they went to a lot of effort on their mid 70s 49.9 Ci 65 horse offering.
Dual carbs, powerflow gearcase, big square exhaust ports, exhaust tuning, high ring pressure back pistons with .070 top ring etc. I don't know for sure but I think they went the wrong way with the goofy piston port intake design.
What do you think????

I thought this would have been a great eng for short courses..in R or For E class..
I started to make the eng..the tower, I was makeing it at the Machine shop class with Yard bird at Napa Jr..built the complete powerhead at home and was going to use a chrysler racing unit on the bottom end.....but as time went on and with wife passing away..I sold the powerhead to some customer while working at D and R marine in Rodeo, Ca.. sold or traded the gearcase to Yard Bird...
still would like to try one on a sport E boat with a good Ron Hill cleaver..Would be a great engine say at Marysville..

Hi Dwayne - very impressive effort. When was this done? Are there any photos of the innards of the tower/tuners? At some stage that engine must have been dynoed - any numbers? Best,Wolfgang

I will take some pics of the tower and tuner when I take it apart....I will be taking 5 inches out of it.

This motor will be fitted with a pair of TC3As, Balanced, flex flywheel, Chrysler quicky, power trim, along with port and CR mods...going to match the piston ports to the block. I have two blocks so I can experiment.

Wow Bill, sounds like a great project. Pse show us some photos as you go along. I want to fit a flex flywheel to a Force4, made up of a billet aluminium ring and utilizing the original hub and magnets. Any recommendations regarding the flexplate material??? rgds, W

Bill, when I shortened my Chrysler 4 cyl long tower, I found out that I only had to cut 4.5 inches, to retain 2 mm gap above the driveshaft stub (where it sits in the crank), for the racing lu. Do you have a test wheel for the Chrysler racing lu? If so, would you be kind enough to send me the main dimensions, so I could get one made up??

Message came out garbled - I was referring to the dimensions of a Chrysler 4 cyl test wheel. rgds, W

never did complete the 65 eng..that was about the time the first wife was really sick..before she passed away..and the old brain wasn't into the eng stuff..and like i said in a earlier post..Sold the powerhead to a customer at work that needed one really bad..the tower and gearcase i gave to Ron or sold it to him..can't really remember..Its been at least 15 years or so ago..
Wolfgang did you get the e-mails with Roys big boat that he just got..Its kind of great..
