We are looking for some performance parts for our 1928 Chevy OHV motor we just acquired. Do any of you guys know where to have a camshaft for this reground with a performance grind? Also we are looking for Aluminum piston or off the shelf alternatives that will fit. We haven't seen one of these motors in a hot rod model T, why ? I know model T motors pretty well so this will be some thing different. After we picked up the motor we took the pan off. We found that the babbit on the connecting rods is excellent and the main bearing also in excellent shape. The rest of the motor looks great inside except for the gunked up screen on the oil pump pickup which is currently soaking in solvent. The biggest problem is the flywheel is rusted to the bell housing, seems mice have gotten into the bell housing and made an absolute mess out of it. The ring gear is shot as some of the teeth are rusted away. The idea would replace the fly wheel and clutch ***embly with some thing we can mate a 3 speed transmission w/ electric overdrive (similar to a '41 lincoln any other tanny suggestions please) and couple it to a banjo rearend that we can easily change the gear set put on till we find the right one( suggestions?) with juice brakes out back. Up front we would like to use dropped I beam axle with '35-'40 jiuce brakes, matching spindles and wide five or 16 " wires on all for wheels. The body will be a full fendered a model T touring with top and side curtains for foul weather driving. I found this one on here and fell in love. Although I would like to do '17- '25 full fendered touring but I Love This car. We are looking for something different and this motor happened to fall into our laps and we figure if we put it back to stock we can still use it, but it would be cool to make it into a hopped up banger motor, just to be different... Thanks for the help, Chris Becker .
Dema Elgin ground my '32 Plymouth cams. Also my Packard and Dave Doziers '39 Chrysler. My Plymouth went 135 on the salt and Dave went 250 in his liner. So Dema can't be too far off. He has a web page.
Since the stock bore is 3.6875, you could bore it to 3.75, which would open up several piston possibilities for you (265 Chevy, 292 Ford, 300 Buick, etc).
One of the most popular modifications was a Oldsmobile 3 port head, I believe there was a Pontiac rod that was also used. Also "B" ford cranks and ,I think, rods. This required some clearance in the block. A fellow I worked for said that in the late "20'" 's and early "30" 's they bought most parts to build their engines from the local wrecking yard.
I would think another person would be Bill Stipe, who both manufactures and regrinds Ford cams, T and A, and has been known to dabble in pushrods.
Hasn't Bill Stripe got a very large collection of cam masters? Ed Winfields old cam masters? He may have Chevy masters there already?
Since it's got a plank style head with no combustion chamber, if you find a 3.75 inch piston with a taller compression height, you can up your compression without having to deck the block.
I believe the Sturgin car is still running. Check with SCTA, they are still running a early chevy 4 I think.
What would the maximum compression ratio be that I could use on the Chevy motor. It definately has a much stronger crankshaft than a model T does. Would there be an off the shelf insert bearing connecting rod we could use? How tall would would be the maximun for piston heighth to gain the most compression ratio.Thanks guys for the info., and I'll look up Bill Stipe and Dema Elgin when I get time. Any suggestions on a 3 speed ovedrive ****** I could start looking for? We are getting the parts for it right now so when we get done with our speedsters we can start on the touring. any one have a Picture of the stugin car in the SCTA I would like to see it if possible? Thanks, Chris Becker
Hi You asked for the trannies. I'm myself looking for a -39 studebaker transmission with BW overdrive. This is because I want the shifter to be on the steering axle, not on the floor. BW overdrive was introduced at 1934, or was it 36. Anyway, several American manufacturers used it since. The -39 Stude is by far the only I know, with a steering shift. If you know others, please shout it out loud.
