Oh know! The old "when I increase the Hp of my motor, what else do I have to do to my car" question.

Let's see.

Will the fuel pump supply all the fuel the engine will need?

Will the radiator cool this beast?

Will the exhaust constipate the engine to no Hp gained?

Will the clutch slip at higher torque?

Will the transmission handle the torque?

Ok, I cannot torture you any more. I think in your case the tires will slip before the clutch, so you are likely OK. If you go WOT in a tall gear where the tires stay hooked, then you can put all the motor torque through the clutch, but the light wieght of these cars, should help.

There is the theoretical Hp/torque increase of more cubic inches, but if the exhaust was limiting the old engine, there may not be a real increase in Hp. However there would still be an increase in torque, below the rpm where the exhaust constipates the engine and clips the Hp. So I would be thinking more about higher torque.

PS
See if you can find out how much torque it takes to slip the clutch. That would depend on the clamping force of the pressure plate, which would be the biggest factor. The coefficient of friction between the clutch and flywheel on one side and the clutch and pressure plate on the other side would be the second factor. However if Brent says he has experience and the clutch is good, I would take real world experience as the gospel.
