Hello, and thanks in advance for your assistance.
Last summer my son and I had a blast off-roading and we ended up in too deep of mud and hydro locked the jeep engine. Now were planning to build it "better" with a 4.6L stroker,

Re: Please review and critique My Stroker recipe
Looks good. However you won't be running 87 octane with option #1. I would also recommend a JP Performance/ Rollmaster for the timing set. Hylift-Johnson for the lifters.

Re: Please review and critique My Stroker recipe
Thanks for the info, I found the JP timing set on ebay for $104, I'll send the other once back.
With the information entered into the calculator on the board I have the following:
SCR 10.57:1
DCR 9.07:1
Quench 0.043
Intake closing angle 55
Any issues with this running the 93 octane fuel?

That will be fine on 93.. you might even get by on mid grade.

Re: Please review and critique My Stroker recipe
Hello again all,
Now that all the machine work is complete I have a final decision on the head gasket thickness that I need some help on.
0.043" gasket will give me a SCR of 9.72:1 and quench height of 0.034"
0.051" gasket will give me a SCR of 9.57:1 and quench height of 0.042"
Which gasket would you choose and why? My goal is to have a engine that runs on pump gas.
Thanks
Aaron

Re: Please review and critique My Stroker recipe
Go with the thinner gasket. The decreased quench distance should offset any problem with pre ignition.

That's why I like setting up my combinations off a 9.450
Block height with a 1.385 CD piston.
Targeting a piston to be .008 out allows for variances that could be made up with the two common choices of head gaskets.
Your piston rings are on the way.
