Yeah, definately go for the 18RG straight off. the one i bought a while ago was built using an 18R-C block, and it took at least two 18R-G's for them to complete the job.
If you're going for an 18RG it pays to check it over well before buying. Some parts that are often missing are the intake side of things, exhaust manifolds/extractors, top chain tensioners and dizzies.
To get these parts separately may take a little longer as people don't like to let some of them go.
"Complete and running" is most definately the best engine to buy.
One thing to check if buying an 18RGU is that the head isn't cracked. I have my doubts about some of the casting in the 88251 heads, as I've seen a couple crack in the same place. Light pressure testing is always worth the $20-30 BEFORE porting the thing!
Best of luck with it,
and if you need any parts, PM me, I might just have a spare one lying around. Almost all of my parts are being put to use, does that still make me a hoarder?Originally Posted by barned01
