Also this re: Building an RB26 for response going off-topic
I am interested in the intended purpose of building this 3.2 torque monster
Just because have the money to build this I am uncertain if your going to be happy driving it.
I'd try and get a drive in same or similar car first.
Everyone is talking block build what else in the drive train is planned. Also Fuel supply, braking, Engine management etc..
For this sort of build plan I have to quote a line in a FnF movie
"It's not how you stand by your car, it's how you race your car"
