Model A Ford 1928-1931 compression ratio = 4.22:1. A replacement "high compression" head from Brumfield raises the compression ratio to 5.5:1. You would not want to go any higher than that because the babbitt bearings and head gaskets will not hold up. You must use grade 8 studs and nuts because they need to be torqued to 65 Ft/Lb.
didnt have a regular rock resurfacer? seems that wouldve been easiest just slide it over it i was using one the other day for some exhaust manifolds woulda been perfect
I have a question for you. I have a 1931 Model A engine that was great running until the piston failed. The wrist pin poked two holes the size of a quarter in the cylinder. Is it possible to sleeve a block with this type of damage? Is it even close to being cost effective? Appreciate a response. I love your vids, by the way!! Keep them coming!! Dave
I have done quite a few heads on a bridgeport,no problem,the bigget head I have done was from an Audi 5E straight five cylinder,alloy head and block.Still had plenty of table either end.
The old bridgeports are indispensable for some jobs,infact there's very little I havn't done or seen being done on bridgeport,plus a good one when they turn up wont break the bank either,It does annoy me thought when I see and abused one of which there are plenty!
keep UP THE GREAT VIDEOS JOHN. ALL MY FRIENDS ARE AMAZED by YOUR PRECISION. id like to see more on small block chev rods on the lathe Thats awesome. take care and check your facebook

A sleeve makes perfect sence for this repair. Cost is in the $150-$170 region.
