Well I'm still in the planning stages of a GT40 build. But I really want to have everything lined up before I drop the $$$$.
I've been pouring over all the stuff online regarding various drivetrain possibilities. I think I've got the trans down as a Porsche unit. I've talked with several of the big re-building companies. I want to build a right-hand drive car and have a right hand shifter like the original. So that means a cable shifter and the Porsche units are built that way from the factory. So probably a G50 or varient.
My dilemma is still the engine. I like the idea of cubic inches. The 351 windsor stroked to a 408 will make gobs of power and torque. But I can't get away from the sound of a 289/302 small block.
This video is what really gets me wanting the small block: 1966 Ford GT40 Mk I. Awesome SOUND - Starts, Accelerations & Fly Bys - YouTube
I know that it's a total race engine. But I believe that a solid roller engine at around 10.5 to 1 compression would really sound great. I don't even know that I would need to go to a 347 cid given that the car is only going to weigh about 2600 lbs. or so with me in it. It seems like I can make an honest 400-425hp without sacrificing decent reliability.
Or do I just go for an older SBF and stick with a standard hydraulic flat tappet cam. I don't see my revving it past 6,000 rpm's much, if ever.
Any thoughts from anyone, especially if you've gone through this would be greatly appreciated.
