Re: South America Jeep Tornado SOHC engine

I was in the Army assigned to a vehicle issue yard when the first M715's with the Tornado engines were first delivered. This was at Ft Carson Colorado. The trucks were driven from St Louis I believe, they were hooked up in tandem,one flat towing another one. Almost everyone of them dropped a cylinde...

One kid had big fin DeSoto with with the dual quad hemi, few doctors sons...

Re: Vintage Ford V8 film

Not all performance guys liked Fords... I met Bill Fisher, aka California Bill, around 1992. He was an well known Chevy 6 and GMC 6 hot rodder the 50's. His name is on one of the several aftermarket heads for those engines and he wrote at least one book on engine modifications .He talked for a long ...

Re: Vintage Ford V8 film

I’m pretty sure the hydraulic brake thing happened because Henry was averse to paying royalties to the Bendix corporation. In ‘39 he finally relented and went to the Lockheed brakes which were not self energizing. Chevy used a non self energizing Huck hydraulic brakes from 1935 to 1950..Maybe a GM ...

Re: "Cocked" rod bolts

Well if it couldn't have been damaged in operation, and it couldn't have been machined wrong when it was made, what the hell is left to explain it? It has to be one of those two things, however unlikely you think either one to be. With age, 60 years, these rod bottom ends go out of round 90 degrees...

Re: "Cocked" rod bolts

Most riders never push on these old turds so as long as the bearing inserts don't fall out all is good. If you like to use all the performance a suspect rod can have an unscheduled disassembly..

Re: "Cocked" rod bolts

Jack, it's true for the original forged alloy rods on the vintage British bikes when the engine is used in anger.
I have no idea if it's true for the aluminum aftermarket car rods.

Re: "Cocked" rod bolts

Thanks....Best to consider the rods as scrap...New aftermarket aluminum or steel rods are available from the UK and USA...$400 a pair....Less expensive than risking sawing the engine in half from a broken rod

Re: LS PM guides, stem clearance?

The .0027” clearance would be considered worn out. With new valves I would have the clearance honed to .001 intake .0015 exh. Put liners in them from k line Today's oils and pump gas don't always play well with tight guides. Rebuilders who do many engines every day and have to warranty them would n...

Re: LS PM guides, stem clearance?

Seems like allot of clarance? I build vintage air cooed bike engines ,not car engines. Using modern single axis valve seat machining, clearances of 001 intakes and .just under. 002 on the exhausts. Bronze guides with seals on the intakes, 5/16 stems.

Re: Vintage Ford V8 film

Those old films are fun to watch.. A few years after that Ford's refusal to adapt hydraulic brakes and IFS let Chevy grab the sales lead... From what I understand the Chevy knee action front suspension wasn't a huge leap forward. Think they offered both styles of front suspension for a while. I fou...
