Is it better to run an aftermarket (approved) Dart or World Products block?
My intentions were to take an old 4 bolt main block I have here and put 8 sleeves in it have it align-bored, and squared/decked. I was tossing around the idea of bronze lifter guides as well, are the worth the effort/cost as long as I am having the remainder of the block machined?
The block I have is not the "same year" as car used and now that I am looking at these aftermarket blocks I am wondering if the additional weight in the casting is worth it to have a more rigid block.
Thanks in advance.

Don't spen al the at money on a old block, Putting 8 sleeves in that block will put a lot of unwanted stress in that casting,
Go with the SHP block and just about all roller lifters now are tall and will work the older blocks and the newer ones with the taller lifter bores.
We machine alot of Dart blocks and are a dealer for Dart products and as Alan metioned they do need some work and we like to have the lifters to be used in hand and fit them if needed.
The Dart block is light years ahead of any OEM block when it comes to cylinder locations, lifter bore locations, and cam tunnel placement and deck heights ETC.
Good luck which ever way you go!!!!
