I have a 5.3 from intake to oil pan I picked up for $150 that I have already torn down and inspected. I'm wanting to build a 383 out of it and i already have some brand new diamond dished forged pistons for the 3.905 bore laying here waiting to be used along with a single Manley 6.125 H beam rod. I'm curious if anyone has any experience with the lunati 4.000 crankshaft or H beams in 6.125 instead of buying 7 more Manleys and I was also curious about what all machine work I need to get done on this block other than the bore/hone with deck plates for the larger piston and the line hone for the main studs or if I would be good with just that. I'm not a millionaire wanting to pour ever last dime into this but I'd like to have a nice engine for my next project so that I can have some fun on the street or at the track on the weekends.

 

Manley and Lunati both make some nice parts. Are you adding a turbo or something?

 

Ok cause I'd like to get a full weight matched set and I'd like to keep it n/a until I decide on what to put it in but down the road once I pick the car or truck I'd like to throw some boost at it whether its a turbo or supercharger I'm undecided it kind of depends on room in the engine bay.

 

I'm running a Lunati voodoo 4" crank in my 383ci. No problems so far, I have about 1,200 miles on it with a procharger pulling on the snout at 600+ hp.
