yep, but these longblocks are built like supra longblocks---nearly bombproof with GOOD TUNING and good gas.
the original hellraiser car had completely stock longblock, dedicated fuel/spark system, aftermarket clutch, stock IRS, and that is about it--made over 1000rwhp--wasn't totally streetable with the stock IRS (would easily break the IRS with traction and full power)
i plan on stroking the motor, and getting a full rebuild with better pistons, rod bolts and head studs--maybe an aluminum teksid block, as they are a little better than the '03/04 iron blocks. this is still just over a year away, so i don't want to get ahead of myself, but it will happen.
