Block Casting# 10066038

Here's what I know:

Made in Mexico around 1992
1.94/1.50 Head# 33417369 76cc combustion
260HP/350TQ
8.5:1 Compression
2 piece rear main seal - 4 bolt main

Nodular Iron Crank
Cast Dish Pistons
Wa told the dipstick can go on either side - this one is of the driver's side


Can't find is this has a flat tappet or hydraullic roller cam?

Can you suggest a replacement oil pan from either Summit or Jegs?

Not sure if this qualifies as a GenI or Gen II Block

Gen I block.A two pc seal lends it's self to be a flat tappet cam.The Yr does too.The hp/tq numbers seems abit high.
