88 stroker

[49 Oliver 88]

got a 88 with the m&w kit head work done runs good but looking fer more power. how difficult is it to stroke it 1.25". I know machine work and grinding is involved but its a wet cylinder. what has to be done to not cause leaks dont really wanna run oil in the radiator. and who is good to send the crank and cam to for grinding and off setting? any info will be greatly appreciated.

where are you located? if you are near ohio, harts in cecil ohio does excellent quality crank and cam work. with that much stroke im assuming you will bore it more as well?

 

[Eddie Richardson]

Southwest ohio and do you have a number fer them? And poking is a consideration if i can do it mildly lol dont wanna leave dii

 

[Eddie Richardson]

Im basicly looking to be around 375
to 390 ci

If you have a 3.875 bore you are looking at a 5.250 crank gives you 371.3 cu. A 5.500 crank would give you 389 cu. Both will work with not alot of grinding with early 77 rods 2 inch jor. You will have to grind a little on the rods, cam and block. You might as will look for some pistons with that size crank. Chevy 283 cu. small block.

a 5.5-5.75" crank is a lot of work and your rod/stroke ratio is not good with 77 rods, Why not bore the block out to 4.25-4.375 gonna have to get new pistons anyway, and keep your stroke at 4.75-5.25,

How many rpms are you turning? Just remember your cam is the weakest link

1926 rpm making round 85 hp great motor just want a lil extra
umph in the heavier classes I run 5000,5500,6000 would like to
pull 6500 and possibly 7500

If you can run a 310 12 port head, that would be a start, still have to bore/stroke it...OR a 195GK power unit

I am at 410ci with a massey 1100 head, makes 140hp @2150rpm...I can pull 8-9mph in 5500lb class....have not gone up to 65 or 75, but should be able to 4mph or better....should give an idea of what you need...

Good guy to call is Bobby Hinton ,@ Hinton Engines he is real sharp!!!

4.375 x 5 is nice. emails open.

Yes-your rod ratio stinks with that small of bore and that big of crank. Also hard on sleeves. If you have 85 hp with just M&W kit wow. And 140hp with 410 cu. again-wow.
Like they said-if your going to all that trouble you might as well go with a bigger bore too. up to 4.375 and still run water.

It dynoed at 80 and have since added alt and electric fan. Its a strong motor holds 150 psi on each cylinder

Iam in south eastern Indiana give me a call I might be able to help you cell 812-707-9336 home 812-432-5581 Keith Gordon

If you bore the top "lip" out on cylinder bores, and have sleeves made that sit on the bottom bore, at the bottom of the water jacket, a Chevy 427 piston can fit. With a mild crank 4 3/8", you'll have 383 ci. Depending on your compression, timing, cam and fuel, 100+ hp is possible. At 10:1 compression, 125 is attainable with racing gasoline.

sounds like big motors has been there. (HI BOB!) try this combo. 4.75 stroke, d19 allis rods, 489 chevy stroker piston from KB. You dont have to clearance the cam or anything. Nice little oliver.

 

[49 Oliver 88]

can I get your email to ask a couple of questions? thanks

 

[RichB]

Mine is 4.125x5.250 421 cid turning 2500rpm,Very strong engine.Billet rods and a solid cam,no grinding anywhere needed....And its been running since 1999,I would say easy 1000+ hooks on the engine.Build it once,build it right and it will last.

 

[Eddie Richardson]

If you could shoot me an email with some specifics that would be great its gonna be a winter project as Im still pulling now but gonna go bigger fer sure and that sounds like a good setup. Thanks

 

[Eric Bloom]

call keith gordon. his number is below. good guy and does great work. would be my first choice. if i wasn't doing it myself.

you can use stock rods up to 4.75 with a little clearancing. or use buda rods. with different pistons. 4.125x4.75 would get you 381 cubes.

4.125 is good, but would still have to bore the block so why not go to at least 4.25....

If it is at 3.875" could bore those to 4.030" and maybe 4.060" and stroke it 0.75"-1.00" would be a little cheaper since already have those installed

The buda rods are good and the massey 65 are too

 

[Eddie Richardson]

What piston would that be for the 4.030 bore?

 

[Eddie Richardson]

Im assuming any chevy 4" piston .030 over will work am I
correct on this assumption?

Yes sbc or sbf will work.... but you have to have wrist pin bushings made and you have to calculate your compression height for your stroke and rod length, and figure out what dome or flat top will work with your compression requirements.......I have a 4.500 stroke 195gk crank with billitt rods for sale if interested give me an email address
