Puting a v8 in a saph isnt hard or difficult, but to do right, isnt cheap
450-500 bhp is easy out of a normally aspirated small block Ford/Chevy
take your pick, but then you will also need all the drive train to go with it,
Tremec box, new prop, diff, driveshafts, add it all up, and even using
second hand parts its not a cheap conversion. Then when youve got all the
bits you need, you need to find someone to put it all together, so the end
result is a good package. This is the hardest part of all imo, and i was very
lucky to have the people that done mine, for without them it wouldnt have
turned out nowhere near as well as it has, if at all.
Before you start id recomend you sit down and plan it all out, and cost it,
then double it , its all the small bits that realy add up. but if you do it the
kind of grunt you end up with, in any gear, any speed, has to be experianced to be believed, good luck, hope you do it.
