[DeTomaso] what have i got?

[SEL]

hi all - bought a car a couple of days ago and among the invoices was one for an engine rebuild the car underwent as follows:

o Bore (.40 over/385c.i.) and hone block
o Magnaflux block
o measure and square mill block decks
o Boil block install cam bearing and plugs
o balance rotating assembly with flywheel and clutch
o Assemble
o Dyno (500HP/472lb torque)
o Keith black KB876 forged pistons - stroke 3.75, bore 4.040, rod lenght 6.125, flat top, 9.8:1 compression
o Plasma moly ring set 4.040 x 1/16 x 1/16 x 3/16
o Clevite CB663H bearings
o Eagle forged crank, 6.125 S/R Rods
o Felpro gaskets
o Comp cam custom grind solid lifter cam and lifters
o Comp cam promagnum rockers and pushrods
o Pro comp alum heads P/N PC3062 - 
o Manley studs, guide plates, L-P springs and ret.
o SA Gear 9 Key tru roller set w torrington bearings
o TCI rattler damper and pulley spacer
o Edelbrock air gap intake manifold (dual plane)
o Bolts, 8 grade
o Moroso oil pan
o Ram steel flywheel
o Melling pump, arp drive rod
o MSD 6420

So here goes a bunch of questions asked out of ignorance:

- i believe i have what is known as a solid lifter engine, correct? - in what way does that differ from a hydraulic lift engine? what is valve lash and why does that seem to be so burdensome with a solid lifter engine? - is there anything special one needs to do to maintain a solid lifter engine v. a hydraulic lift? - why do people alwasy question whether a solid lifter engine is "streetable"? - why wouldn't it be?

- with respect to these heads, are folks familiar with them? - i believe they are from australia - what positive attributes do they have? - anything special about the design (flat top) or build?

- what do people think of this build generally? - is it a high quality build? - does this seem like a "streetable" engine or one that is designed primarily for racing?

thanks
