sanders356 Posted August 17, 2013 Share Posted August 17, 2013 Hi, I'm new to the site and would like to seek to advice about my plans. I have a 1973 manta a which i would like to put a chevy v8 crate engine and tremec T56 gearbox into. I am wanting to know which would be the best axle to use. My preferred option would be to use the standard axle with a quaife LSD fitted but not sure if the ratios would be correct or whether the diff/shafts are upto the power of a chevy v8. Can you buy uprated ones???. I have also thought about a volvo 240, ford 9", commodore gs/e axles as well but don't know enough about them yet. Any info would be much appreciated Cheers Sanders356 Quote Link to comment Share on other sites More sharing options...
Beaker Posted August 18, 2013 Share Posted August 18, 2013 I'm no expert on this type of mod, but a few years back Paul Holtom built a Rover V8 powered A series, he used a lot of the running gear from the Commodore B to cope with the extra power and torque. There's not a huge amount of space between the chassis rails of the Manta which has been a limiting factor for a lot of people in the past. Having said that, I once saw a Jag V12 shoe horned under the bonnet, scary. Quote Link to comment Share on other sites More sharing options...
simon p Posted August 18, 2013 Share Posted August 18, 2013 Lots of options, what do you want to use the car for? How much torque will your engine be making? Quote Link to comment Share on other sites More sharing options...
sanders356 Posted August 20, 2013 Author Share Posted August 20, 2013 Hi, I've got my eye on a crate engine 6.2L chevy 430-480 Bhp. The car will be a weekend toy to be honest i only managed 1600 miles last year. I would like to take it down the strip just for a timing ticket but this really isn't why i want to build it.

sanders356 Posted August 20, 2013 Author Share Posted August 20, 2013 Hi again, Just had some info about a rear axle - Salisbury 4HA axle allegedly good for 500+ torques, 500BHP and plate LSD fitted as std. Anyone got any thoughts about this. Cheers Tony Quote Link to comment Share on other sites More sharing options...
rutts Posted August 20, 2013 Share Posted August 20, 2013 good axle but very heavy, similar width as a series axle. does not have a plate LSD as standard you get one out of a jaguar then have a bit of machining done to make it work. Quote Link to comment Share on other sites More sharing options...
bones Posted August 21, 2013 Share Posted August 21, 2013 A Ford 9" should be pretty bulletproof you'll not blow that up, it'll be heavy but virtually unbreakable. Quote Link to comment Share on other sites More sharing options...
mantaray Posted August 21, 2013 Share Posted August 21, 2013 Simon P can do a conversion on the 4HA axel so that it will fit a Manta using the original pick up points, ( he is currently doing one for me) Well worth giving him a ring.
