I apologise in asking, what to you guys, must seem such a basic question .
What should I get rid of on the puter, what should stay ?
The 'rough' changes to the vehicle are as below
Remove the existing 307 olds and replace it with a 66 toro 425 10.5:1 .
The replacement carb is non ccc .
The intake mani. is an O4B .
The heads are currently being ported and polished . These will take a set of headers( custom no doubt !!) .
The cam won`t be wild (hyd. lifters and stock rockers staying)
The trans was to have been a th400 but am now going with a strengthened 200 4r .
The final drive ratios will be 3.08 to 3.23(NODIH has kindly given me the low down on the options here.)

That said , I am after someone in the not-too-distant future to see to the impending alterations .Sure, I am a long way from the states but happy to pay the extra postage .
regards mike

Get rid of the computer. Actually, keep it, but only to run the climate control functions. You just have to put the sensors from the 307 into the 425...

I doubt the 200 4R will last very long behind a 425, they barely survive behind a 307

You can build a 200R4 very stout, some turbo buick guys are running 500whp through a built 200R4.
