I'm not too concerned about the fuel since it won't be a daily driver but all of the mods associated with it are a bit discouraging. Im trying to keep the truck mostly original (except engine of course) without cutting anything off such as the crossmember. The 261 would be so much easier but I guess that is the reason they are hard to come by.
In regards to the cost of the 291s are they to pricey? I have seems couple up north that are a lot cheaper but I think the market in the Dallas area drives prices up. Also, what could be done to check the engine since it isn't running? Compression?...
Thanks for the feed back!
