Pair 509 motors
 

Unfortunately life happens and I have to sell my motors. These are new zero hours (blocks were fresh water use) all machine work done by express engines in DeLand they have an excellent reputation
blocks were line honed
lifter bores checked
bored with marine tolerances
rods were sized and fitted with arp bolts and fitted with je flat top pistons
oil pump was blue printed and pickup welded
express did the heads as well they built from blank EQ heads and fitted with inconel exhaust and stainless intakes along with valve springs that are matched to the new 525 EFI cams Stainless roller rockers with 7/16 pushrods and new Imco valve covers
new gm high performance timing set and lifters
‘cometic head gaskets and arp head bolts
new sea pumps, stainless t-stat housings, water circulation pumps and mercury sensors Temp, oil pressure, oil temp
hp500 oil filter/t stat housing with new thermostats and 3” oil coolers
new ATI balancers rotating assembly’s we’re balanced with these and merc fly wheels that come with these as well
new bravo couplers and bell housings They sit on vhull off shore mounts
victor jr intake that has been port matched to the heads 960Ish aerosol carbs and large oval marine spark arrestors
No harness or ignition Or exhaust
I am sure I am forgetting something these were built to last by the best people I know in Florida
These are 99% there
