OK pop quiz all you gear heads . Heres one hot out of the truck box tonight. Anyone know what it is? Which car company manufactured it and what is it's displacement. Hint... It was introduced into production in 1959 untill 1971.

Oldsmobile 455 Hi-compression short block ,all machining finished,new parts installed and assembled. Ready to ship

This is the head to the 215 Plymouth. It needed quite a bit of milling to get the surface clean end to end. Material removed .025 so we'll be making a correction to the gasket. On the good side it's gonna raise the compression a slight.

Clean block, decked and boring to fit the new pistons. some valve guide & valve seat work and then off to be honed.

This teardown is an older girl from 1954. Its a plymouth Cambridge with an inline 6cyl 215ci flat head, tired and dirty. This will need a more delicate approach to clean up but should come out ready for machining. more to come....

Back in July we picked up a few core blocks at a swap meet. Some Oldsmobiles 455 and Clryslers 383. Teardowns and clean up ,machine Olds.

Number 2 in line was a 3.8 V6 Chrysler Jeep. Nice and shiny,deck , bore & hone. Tiny too! This one is going for stroker status 4.1 and lots of head work with some go fast power options. More pics to come!

Cleaned up like new cast. This was #1 of 3 to deck & bore today, older 5.7 chrysler.

Here's one you don't see everyday but we see often when we're building race pieces. Customer asked, can't get the new intake to line-up or bolt down. Can you machine the intake to fit my engine? Custom engine builds do at times need some (little or allot) fitment. We milled .130thousandths off deck and .180 off the china wall ends. He says it fit perfect!

Finished up the machining, getting all the parts around for this Chevy big block, get the short block assembly together. Heads are close, still waiting on valves and springs to match the camshaft.

Finishing a short block set up 455 Oldsmobile. Hi compression L2323 speed-pro pistons to a nicely balanced assembly. Homeward bound today. '70 cutlass convert
