Swapping out a pair of 454's with some newer 8.1s. I know that the 8.1's are about 1 1/2 inches taller but I'm also going from Borg Warner 72 transmissions to Hurth 63A downangle transmissions so the engines will need to be lifted up a bit on the transmission side to match up. Does anyone know about how much it needs to raised. I currently have 4 1/2 to 5 inches of clearance between my existing flame arrestor and the hatch. Will I have enough room? I also know I'll need to get longer shafts. Can I just take the difference between the lenth of the two transmissions and add that to my new shaft length, or is there more to it than that?
Maybe Linesix would know.
Thanks for your help.
