i was wondering if anyone has ever purchased or know someone who used a 460 crate motor? i have heard good things about the jasper motors and got some info from them on their class 2 & 3 motors. they come with a 7500 mile warranty & have approx. 385hp & 485ftlb. of torque. price is slightly over $3000. would a machine shop rebuild be worth doing or more economical? motorsport crate motors seem very expensive and offer no warranty, but seem like great packages. any input or experiences would be great thanks.
No personal experience with buying a crate motor, but the only way you're going to beat their prices is to do your own disassembly/assembly.
I used one of the PAW disassembled shortblock packages several years ago and was very satisfied with their quality. A PAW 460 longblock is now about $2k, and that includes forged pistons, moly rings, choice of cam and C/R and premium parts. You assemble. I'm currently in the process of doing a new 460 and, heads aside, furnishing the same shortblock parts and having a local shop do the machine work was about the same cost as the PAW shortblock on an identical parts basis. Hard to beat.
Ford crate 460s, $5k for the entry level, are directed towards the car crowd, which requires a cam and intake manifold change for most long block truck applications. You have about $2400 of that cost involved for aluminum CJ heads/valve train and another $600 for manifold, distributor, pan, etc.
The lower end price Ford shortblock (same as used in the $5k crate engine), approx $2k, uses hypereutectic pistons, so when you compare that to the PAW shortblock with forged pistons ($1500), it's no great deal as a shop will only charge $150-200 to assemble most V8s to your specs.
Don't know anything about the Jasper engines, but most prices and quality for crate engines other than those with good heads are about the same.
