Considering the TA block
I'm probably a few years off w my TTA, but am considering the TA block and talked to them. Sounds pretty good, and hopefully the initial problems, which pretty much always happen w a new product, have been ironed out.
I guess they have 6 bolt Mains and no need for a girdle, so when U add that in the price is not so bad after all. I guess they can even go w a stroker crank and get U as much as 274 CI - at least a 15% increase. They also have their own forged cranks, roller cams, 14 bolt heads, headers and intakes and a few other goodies as well. I might consider just having them do the whole job.
I have some worked iron heads for my TTA, cause I guess I can't get any Al ones. Not sure how iron heads go with an Al block ?
