staledale Posted September 20, 2007 Share Posted September 20, 2007 Does anyone have the dimensions for the Chevy bolt pattern so I can build an adaptor? The other side will be Jaguar, I can't seem to find the Chevy, hate to see what it will take to get the Jaguar dimensions. Least I've got one of those out in the garage. thanks Staledale Quote Link to comment Share on other sites More sharing options...
bschiltz Posted September 20, 2007 Share Posted September 20, 2007 Are you using the chevy engine and Jag tranny? I'm sorry I don't have the dimensions for you, but I'm interested in seeing what you're doing. Quote Link to comment Share on other sites More sharing options...
staledale Posted September 21, 2007 Author Share Posted September 21, 2007 HI, I have a 250 GTO rebody that I will put my Jag v12 with weber carbs in. I'd like to use an overdrive tranny 5 or 6 speed with my 3:31 jag irs rear end. I need an adaptor for bolting the chevy bellhousing to the jag block. I'd even go for the dimensions for a Ford bellhousing. thanks Quote Link to comment Share on other sites More sharing options...
Administrators BRAAP Posted September 21, 2007 Administrators Share Posted September 21, 2007 This should help get you started. This print shows the rear of the “Small Block Chevy†block including bell housing bolt hole pattern w/dimensioning including crank centerline etc. Please keep us posted on your progress, including pics...

Scottie-GNZ Posted September 24, 2007 Share Posted September 24, 2007 Many early Jags used the TH400 tranny. Might wanna look into what they did to make that work. Quote Link to comment Share on other sites More sharing options...
Turbo6inKY Posted September 25, 2007 Share Posted September 25, 2007 Many early Jags used the TH400 tranny. Might wanna look into what they did to make that work. I do believe GM cast them a different case with a bellhousing pattern for the Jag block. They're rare. Did the same thing for Rolls Royce, too. Transmissions on those generations of cars were the only reliable part IN the cars, too. Quote Link to comment Share on other sites More sharing options...

staledale Posted September 26, 2007 Author Share Posted September 26, 2007 Trevor, thanks for that site,that would be my best bet. Save a lot of work. Scottie-GNZ They made the bellhousing on the turbo 400 with the Jag bolt pattern, I've got one but can't see this car with an automatic tranny. Thanks guys, there is a lot of good info here.

dot Posted November 15, 2007 Share Posted November 15, 2007 http://www.5speeds.com/v12bell.html Great! Isn’t that just about 10 years too late. I had to build one. Dale for the flywheel grab an old chev unit and mill it flat on the back. Bolt it over the Jag flex plate containing the ring gear. The bolt patterns are the same. You will have to make a small centering ring made for it. I gave a prepared one away last month when I sold the V12Z...sorry... Quote Link to comment Share on other sites More sharing options...
staledale Posted November 17, 2007 Author Share Posted November 17, 2007 Hi Glenn, Can't believe you sold your V12Z, what's next? Thanks for the flywheel tip, I'll have to go out to the garage and play with that for awhile. Got side tracked this summer and didn't touch the Z at all. Just picked up a repoed Vette to fix and I promise the profits will go to the 250 GTO V12. thanks again on that flywheel. Staledale Quote Link to comment Share on other sites More sharing options...
dot Posted November 18, 2007 Share Posted November 18, 2007 Hey Dale Every one keeps asking what is next. What could follow the speed and agility of a hybrid Z? Nothing as far as I’m concerned. A change of format and a little more refinement is required for these old bones so I opted for an Aston Martin DB7. I pick it up Tuesday. I hope no body minds if I still hang out as this is more of an information and knowledge exchange site than just what the name says it is. There is still a lot for me to learn here.

staledale Posted December 2, 2007 Author Share Posted December 2, 2007 Hi Glenn Did you pick up your DB7? They are neat cars, I got to sit in the James Bond car at the 64 worlds fair. No one at the fair that day and the girl standing by it saw I had more than a casual interest in it and let me under the velvet rope. That was neat for a 13 yr old. Got Pictures of yours? As far as you hanging out here I hope you do, you've got a lot of info stored up stairs. I know I'll need to pick your brain. Right now I too have gotten off the Z car path and bought a Corvette off E-Bay. I promise to use the profits from it to finish my v12 GTO. Good luck with that DB7, are you going to leave it stock or maybe put a DETT26 in it? LOL Share some pictures please. Staledale Quote Link to comment Share on other sites More sharing options...
dot Posted December 8, 2007 Share Posted December 8, 2007 Hi Dale; Before I forget the pilot bushing for the back of the jag crank is a standard size. I was going to going to have one made up but the machinist found one in a catalogue that fits. Just ‘mike’ the dimensions off the existing parts and Google. At the risk off hijacking your thread I must say the DB7 is a fine car. The super charged six puts out about 335 HP. But with computer mods, pulley changes and other things then 400 is possible. To be honest I am very happy with the stock configuration. Five speed standard with a 3.5 possy diff. round off the power train. This is the only picture I have right now. After the screaming V12Z with the bone jarring handling, the ride of the Aston is as smooth as glass but what really blows me away is how it sticks to the road. No this car won’t win many challenges, but is this the kind of street ride that should be involved in all that? The DB7 is very much a gentlemen’s sports car and one I will be quite happy to grow old in. Oh ya, there is life after Z. The only thing that pisses me off, is having to spend another twenty years with out a cup holder. Cheers; Glenn Quote Link to comment Share on other sites More sharing options...
Guest freefuel Posted December 29, 2007 Share Posted December 29, 2007 Anyone have the dimensions for other GM engines, like the Buick and Pontiac V8s? The metric or small pattern would be nice too. Quote Link to comment Share on other sites More sharing options...
