Default Jeep Engine Build

I've been showing bits and pieces of this engine build on my '29 Chevy roadster PU build but thought it might be of some interest to a few of you. I have a Crosley wagon that has been laying dormant in the back garage for about 3 years now. It has a 406 sbc in it and runs in the 10.30's At my age that is a bit faster that I care to go.

So, I've become interested in Jeep stroker engines. Take a 4.0 liter block and put a 4.2 liter crank in it and you get about 280 cu. in. A very mild one makes 300 horses.

That will propel the 2,200 pound Crosley quick enough for me.

I had to buy 3 different Jeep engines to get the good parts. One 4.0 for the block, one 4.0 for the head, and one 4.2 for the crankshaft.

Here's a pic of the intake that had a throttle body on it. Now converted to carb use.

Been keeping a list of expenses which some of you might find interesting.

3 core engines $300
Pistons $100
Rings $100
ARP rod bolts $55
Sandblast intake $20
JB Weld $10
Grind Crank & provide bearings $305
Clean, mag. bore, hone, cam brgs
Recon rods, install rod bolts
static balance rods, pistons on rods $426
Brass core plugs $20

Total so far is $1,336

I brought the block home so I can fit the crank, and piston/rod assembly to determine how much to mill the block for a zero deck. Then it goes back to the machine shop to be finished.
