boxes of "new" parts and old greasy stuff got dropped off at the machine shop today... they are still waiting on the rotating assembly parts to show up... but they can fiddle with greasy old junk while they wait...

Gt40 heads are well worth the effort, along with 7/16s screw in studs, roller rockers and a girdle. With regards tot he short block, unless it's an ultra rare 271hp version, it will have 2 bolt mains, You can buy 4 bolt mains for it but you'll have to machine the block and line bore it, a good recommendation if you are going to track it.

the block is a 1989 5.0.. it is being built with girdles etc.. rated to 7000 plus rpm... will be setting the shift light at 6000rpm... had a 1990GT back in the day and learned how to drag race & autocross... anything above 6000rpm still makes my heiny pucker... lol
 
Low 6000 RPMs to maybe 6500RPM may be doable without risk, but it may not help that pucker problem that may accompany that............even in the Boss, after 6000, I.m in unknown territory...for good reason, I suppose...............

an update???
well popped by the machine shop to see if anything has changed.. (hoping for a birthday present...lol)
the update was the cam was in and the motor is much less greasy and the heads/intake are ready to go... but the stroker rotating assembly delivery date is a very tentative late September as of today.. so maybe an anniversary present??. lol
this has been going on starts & stops since 1991 so 2 months is no biggie...
