I had a 1986 IROC Camaro and was going to put a bored 400 into it-even got the license plate IROC 406---------However, many other things took up my time and never got it done before lady painting her finger nails t-boned it and totoled it.

The 400 block I added splayed 4 bolt main caps to 3 center webs, had Brodix aluminum heads, roller cam/lifters, Crower rockers etc-sold to a friend for his car-----------

I built several of them for dirt track circle cars-------a few used spacers in the mains and 302 crankshaft-------killed some torque out of turns and added lots of RRRR's for staight away
