[COYBILT]

well I thought I would put up some pics of the motor when we built. Mind you this is last year. We were using a solid lifter cam(256,262@50 640/660lift 110 lsa, victor junior, 850 demon, ported 72cc edelbrock performer rpm heads,swirl polished ferrea valves, comp bee hive springs,locks and retainers,crower 1.6 roller rockers, eagle H beam rods, eagle cast steel crank, cheap yet effective modified speed pro pistons, Clevite 77 bearings, Butler billet 4 bolt steel main caps, blue printed melling SD455 Oil pump, Milodon windage tray, canton road race pan with pick up, MSD mechanical advance distributor, ARP bolts on everything, Dougs number 567 headers and a Flow kooler water pump.
Its a 73 XA block 455 bored .030 over=462
I had fun remaching every part of the block,measuring every clearence, file fitting the rings, dishing the pistons.090, Deburing, chamfering all the gallies ,etc......
I removed all the flashing, and useless hunks of crap on the block.
The only thing that was reused was the block, two main caps (1,5),and oil filter housing.

that combo through down 619 hp and 677foot pounds of torque on the dyno

with some tweaking we got 629hp @6100 and 690foot pounds@ 3600.
this was done on a superflow 901 We pulled the brake at lower RPMs but it wouldnt hold.

Now I pulled off the manifold and put a BG tripower setup and ditched the solid lifter cam and pulled the oil restrictors. I put a comp cams XE294 cam in which is 250/256 @50 and 552 lift intanke and 568 exhaust with a 1.6 ratio rocker. The cam is also a 110 lsa we installed it advanced 2 degree's. we have yet to dyno the motor and se what it throws down. im guessing 565-600 hp and torque over 600 probaly.
