Re: What spring rate should I set with stock springs and an 8CM camshaft

That is not possible. It doesnt get to 45 pounds until well after 1.800. At coil bind, it barely hits 80. These arent even close to being OEM spec.

I will call Goodson and see what they have. I...

Re: What spring rate should I set with stock springs and an 8CM camshaft

.
I am going to have new seats installed along with new valves. My guess is that the installed height will come in well below 2.00 inches. I had an engine shop for 10 years. I know about wear from...

Re: What spring rate should I set with stock springs and an 8CM camshaft

It doesnt nee that much spring... An 8CM is considered stock. With a .060 shim, the stock new OEM spring will be perfect.

Re: stock NOS fomoco valve springs on a 236 @.050 .355 lift cam

I found some NOS stock springs from 1955 for $70 plus shipping.

There is so much room to coil bind That I could easily shim .060 to >080 and still have .080 to coil bind on a .355 cam.

Should...

I am building a 4.125 by 3.312 stroker. It will have dual carbs with 43 main jets, and a delta 236 effective at .050 .355 lift cam. Something like a stock Merc cam. I found some NOS fomoco valve...

Re: 1951 Ford F3 stroker questions

I am just doing a low compression stroker. I have seen much of your excellent mechanical advice, but I have yet to hear anything related to a flathead 4 bolt main. Anyways, it will just be a low...

Re: 1951 Ford F3 stroker questions

I cancelled the china crank order. I found a 4.125 stroker Merc crank that has already been ground and plugged. I do have to buy Scat H beam rods. What pistons should I get.

Re: 1951 Ford F3 stroker questions

I ended up ordering an eagle 4.250 and some Scat rods. Some chromoly coated rings that are metric would be excellent. I am fairly certain that they are .080. I cleaned the tops of the pistons when...
