    Hmmm... We say 3.75 stroke and 4.600 bore! Can you say 9000 RPM Buick? Our race port version Bulldog head should do.

    We already know the thinnest wall thickness we found at 4.5 bore was still a good .250. I don't see any isuues with going to 4.6 if someone wanted to. Jim

    ah-hee. you guys are too much. too, too much.

    Earick is going for 499 ci @ 9000 rpm. if he uses stock length rods that'll give him a R/S of 1.76, fairly decent. but i'm thinking he's showing a lot of confidence in that new oiling system / smaller main bearing. :TU:

    Jim is saying 598(.28 :pp ) ci. one thing i'm noticing on the spreadsheet is that it's going to be difficult to get a decent R/S ratio with a 4.5" stroke. even the 7.1" rod that Bruce Kent used in his masters motor will only give you 1.578 and the standard TA stroker rod @ 6.8" is 1.511. TA does say that they will custom make rods up to 7.35" and that would get you back to 1.633. that isn't great but it is serviceable. only problem is that the custom rods are aluminum. course, i guess we are talking about custom blocks, cranks, heads and pistons ... might as well go all they way, hey? :laugh:

    yeah, i know i shouldn't be trying to find off the shelf parts for the more outrageous versions of this thing ... i can't even afford the block. :ball:

    something else, are there any plans to give this thing the option of a chevy / gm bellhousing bolt pattern? i would think the bosses for that would be done in casting so it's not likely to be easy....

    it would certainly open up the tranny options that could be used with this thing. a new 5 or 6 speed manual sure would be nice.

    Sorry, if you want a chevy bolt pattern, it aint gonna happen. Don't feel this is an issue, with this kinda power on tap, an ultra bell bell housing should be the norm, and they have both patterns already, either 3speed or 2 speed versions. Jim Burek

    My plan at this point is to use a conventioanl oil pump set-up, maybe with the scavenger plate.
    One of my ideas here is to build a fairly basic big cube motor for street/strip type use. If you can buy a 572 chevy crate motor and stick it in your street car, we should be able to do the same thing with a Buick ,No?

    At his point in time , my focus is to start building 500 plus inch Buick streetable crate motors that are dependable .
    There are plenty of guys out there planning on pushing the performance of Buick v-8's into the 7's and probably 6's. I will be doing a few of these for customers as well.
    But for me personally, I am not looking for a 7 second car, just not my thing at this point.
    2005 is going to be an eye opening year for Buick performance, I can tell you that. Jim Burek

    Bell housing bolt pattern is not an issue as Jim mentioned the ultra bells already have both patterns Even my clutch can for my liberty has both patterns The only thing I would have liked to see was a drivers side starter option so I could run a full length oil pan kickout.But all in all I'm not complaining I can't wait to see my block.
