Stroker CrankClearance?

[James Thomas]

Ok for you fellas that know...... How much if any clearancing is done to Bowtie blocks with the 3.750 stroke crank's? I ate real hot chilli last nite and had a heartburn induced dream that a 4.00 stroke crank would work in a Bowtie block (even fire at that)? Along with a 4.030 bore, Oliver 5.700 rods and some one off JE's that should be 5.0L territory. I know the rod ratio with 5.7's aint' great but I don't think it will see the high side 6k rpm. Any thoughts..... good, bad or ugly :rotf: ? Any of you vendors wanna PM me some prices if it will work? I want to get the cubes but not go 4.155 on the bore.

Why dont you just look into buying the bowtie that Nolan's got for sale and be done with it?

Not much clearancing with 3.75 stroke (depending on rods) so a 4" would fit but there would be some more major clearancing and you would want to use a less bulky rod (Manley / Oliver....)

I would but it's a 4.155 bore and thats maxed out, also what I am trying to avoid in the event that the cylinders need a re-bore. If the 4.00 stroke will work, I get 301 ci. with a stock 4.00 bore, 306 ci. with a .030 over, 310 with .060 over or 325 ci. with the 4.155 bore.
Point is I can still rebuild if there is a whoopsie that requires a re-bore :tup:

Ok, Scat and Bryant both can do them. I know the rod ratio aint great at 1.4 but if it won't make 1200 - 1300 hp on pump and meth with the turbo set up you and I were discussing (yea I decided to go with your "BIG" recommendation) by 6300 - 6500 rpm.... then I'll prolly just break it anyway :rotf: . Oliver's are already on the menu, Paul at JE says the slugs are no problem and looks like the Brodies may happen :tup: .

PM me the info for a even fire rotating assembly (one pcs. rear main), cam and block clearancing costs and the "what to do" to get my block to you / customs info. I hear such horror stories about Customs in the Great North :rotf:

4.155" is not max. You can go 4.165 / 4.175 / 4.185. We sonic tested Nolan's block at 4.155 and it still was over .200 in most places so another .030 overbore is only .015 off that thickness number.

I will send you some info on machining and shipping as well.
