4.1 Rod & Piston Package

[BlownV6]

For you guys looking to build a 4.1 block. Ive been watching people asking about where to find rods and pistons. Strarted looking at my piles of parts and came up with this type of deal if anyone is intrested. Maybe should post in the for sale section but I figured this might stir up some conversation on the subject.
Brand new Wiesco pistons 4.020 bore that have been coated on the skirts , 1.200 CH and a set of Carrillo rods 6.650" narrow journal, off-center(stock). This would allow you to put this combo in a 4.1 block with a stock 3.400 crank. If you do the math with the 3.400 stroke + 1.200 CH + 6.650" rod thats a deck height of piston at 9.55". $450.00 shipped if intrested. Others available.

PM answered!! Those pistons are 4.020 bore. Edited post to show that!!

Would the production 4.1 blocks live with a 4.02+ bore?

I'd be a little concerned. A 4.1 production block on high boost at .055 thousands over standard. Have you got any 4.00 or smaller bore pistons for the same combo, if so I'll bite?

Bump for an awesome deal!

CHARLIEF1 Your rods are on the way. Thanks Mike

Aj , OK worked on your stuff. Final compression ratio would be 8.52 to 1 with that 9.543 block.
Compression height of piston is 1.190 and would put the top of the outer ring on piston at .003 down in the bore. Doesnt get any better than that!! See pics for more info. PM ran out of characters. Mike

Hey blownv6, do the math for a 4.1 and see what you get.

Sorry ,your going to have to simplify this for me. That is a big site and I have no idea what you want me to look at!! I need bore , stroke , rod length , checking distance on piston , CCs of both the piston and combustion chamber
and the bore and thickness of the head gasket you want to run to make an accurate calculation. Mike

 

[charlief1]

Look at the calculators at the right side of the site. All you need to do is plug in the numbers. Saves time and then you can look up pistons if you want to.

Mike,
Did you ever sell the rod & piston combo for the 4.1?

 

[charlief1]

I bought the rods from him. Sorry.

 

[BUFORD93]

With as many parts that Mike has you never know.

 

[BlownV6]

Sold a few sets. Still have a few more!! What bore size and compression are you shooting for. May take a couple days for me to get back with you but I will. Mike

 

[BUFORD93]

I will be starting out with a production STD bore 4.1 ( I will have to bore it ). Looking for 8.5 to 1 to 9.5 to 1.
