Personally, I don't think it'll work. They are 260+ hp depending oin year and the front end won't be strong enough, nor will the rear. I hope that you are running a 4 bar with panhard rod and at least a volvo 240 axle?
Strut front (modified capri) would be good or an IFS of another motor (jag, P100). Then there's the chassis, it'll need some mega bracing to handle that sort ot power and torque, probably easier to build a new one.
I had a twin turbo'd V8 morris with a braced basic chassis (4 x 2 rails) and it started to pull itself apart!!! Big numbers sound good (300hp) but you will need to do a hell of a lot of work to make it safe.
I'm putting a twin turbo'd TVR motor in mine, easiest route is to use a rolling tvr and stretch the body.
Nice chioce of enginer tho, there IS NOT and bolt on manual conversion (looked into this a great length) although you can get kits from Australia or Thor racing but they weigh in at well over a grand a time.
Anything I can help you with then let me know.
