Why would it need to be in an IA block? Are short stroke cranks breaking blocks?

I was talking about a way to increase bore size without (unnecessarily) spending four grand on an aftermarket block. To get a 4.350 bore size doesn't require a $4K investment. Since you're the owner of a machine shop, you tell ME what YOU charge for sleeving and finish bore/hone. That'd save me the time of calling around. Besides, YOU are my favorite Pontiac Machine shop, Big Boy... The Hard Blok I can do myself.
Stick with the initial comparison: using the factory block to achieve a 4.350 bore. Your praises of the features of the new block are duly noted. But they have nothing to do with the initial topic: bore sizing. There are plenty of folks out there running 8's without them (new blocks and cranks). Reliably. And there have been for years. However, if somebody wants to use 500 hp shot of N2O (not "NOS", which is a brand name) to push a 3700 slug into the 8's, perhaps the new block is just the ticket. Or perhaps, maybe so too is a factory block with turbos. But, if the goal is to be able to say "Hey, I pushed a 3700 lb. slug with power windows and air conditioning into the 8's and it only cost $50K in aftermarket glitter items to do it", then perhaps a $4K block should fit into those plans rather nicely. Later. [This message has been edited by Scott Misus (edited 12-05-2000).] |

For the hearing impaired.... "4.350 BORE"
Big bore, short stroke. If it's possible to get that out of a Stock Pontiac block, Scott, let me know which block is the one to use and I will buy it. Yo, duh!!!!! |

4.350 in a stock block is not feasible. Believe me I spent many nights awake thinking about it. Whitmore used to sleeve to .100 plus over (4.250) and had nothing but problems. As half-inch said the remaining material (what little there is) is to unstable and prone to cracking (thin). The 64 Classical Gas GTO (Beautiful car) used to be a test bed for this project and it failed miserably. At 4.350 you may as well take four sleeves and wrap a rubber band around them. It will probably hold together better. Or maybe some duct tape...hey wait a minute...got to go, talk to you guys later!

It was done. Successfully. In 1980. With a Reynolds block, no less. |

I had an OHC6 block with a sleeve in Cylinder #4.....It runs fine.
I saw a 73-SD455 Block with 5 sleeves. Though I showed misus to it. The stroy was that the block originally ran hot in the original SD car. Prognosis was the Pontiac dealer authorized sleeving back in 74 for fixing the overheat. But 4.35" bore.....I'd look into a modular block: Crank/Cam/Bellhousing Block with bolt-on Cylinder banks using really long headbolts. Hmmm, 4-bolts per cylinder is makeing more sense.. Wobbly but neat.

P-Dude ; you crack me up over here with your intact logic with the 4.350+ bore RA V type motor.
Scott ; 8 sleeves makes for a wobbly block. Somewhere around 9000RPM the 90degree Vee becomes a substantially 180 degree flat.

hahahahaha!
A 397"? Is that what a 326 block with a 455 crank would work out to? hahahahaha again! So would it be better to run a set of small-valve or large-valve heads on that sucker? Oh boy.... -Will

Scott, explain how you are going to sleeve the block to 4.350. And what are you going to use to center the sleeve when 3/4's of the wall is gone by boring, let alone the cutter trying to work? And sizing the sleeve so they are flat against each other. I don't think (and I will check)that you can put four sleeves together, with proper thickness, in line and it will fit in the bore spacing of the Pontiac parameters. later.

To just do a block Race prepped all the way and then install 8 sleeves that still won't go to 4.350 and have any strength. Around $3000. But I wouldn't do it anyway. Scott the "ORIGINAL" topic was unique combo's and I thought this would be neat. Big bore, short stroke. You hammered me on the Block choice, I was just wanting to twist a Pontiac to STAR TREK land like the BBC's do and make some HP in the upper rpm ranges.
You once again took it upon yourself to change my choice of combinations and re-apply your ideas to my post. Scott, can ya feel it? LOL. Later. http://PontiacPower.cc |

Dude, Do you think Scott might be qualified enough to be tear down boy for your cheaper cores?
