Your goals should not pose a problem with the right combo.

However, make sure you double and triple check that MoTown block, they tend to have "issues" in the machining department...

Oh Yes, definately will do that...Hey where in the central valley are you located? It looks like you and I both have a mutual friend in Manteca! -Rob

Manteca? Let's see who I know there... Ned for sure, and also Walt @ Performance Machine... my Dad used to drive Walt's Top Alcohol Hydro "back in the day" when you could do 180+ on the water in an open cockpit with no seatbelts and an open faced helmet. :yes:

I'm just up the road a few minutes more in Lodi. Another friend of mine in the area also has a very good machine shop and builds engines well enough to have won the Pro-Stock truck title 3 times in a row.

Cool! Yes I know Walt as well, he did all the machine work on the block I used to build my 383.

Congrate tom good infomation in that project what car is that motor going in? :thumbsup: :thumbsup:

Project car
 

Thank You.We are building a 73 camaro for David Freiburger.for drag week.The goal will be to drive 1500 miles in 5 days while stopping off at a race track every day and racing it.My plan is for the car to go in the 8's and drive like a kitten.Will see i'll keep you up to date.

So rob... you bought a Motown block... copycat !!!!

I was planning on running Cometic gaskets but I'm not going FI, so its not as much of an issue for me...

Troy... machine issues with the Motown blocks..... such as ??? I was planning on having Walt double check everything, but was curious on what you've seen "wrong" with them "out of the box" ??

Ned I thought you had bought a Lil' M? ...I must be getting old.

Anyway, my MTown block is sitting in Charlotte at my brother-in-law's. He bought it for me thru the team he works for. He is having his buddy do the machine work in his "spare time"...which means, it will take forever and a day, but I'm in no big hurry...lots of work to do on the car...and the team's machine shop is pretty competent...so probably worth the wait...:D

My concerns with head sealing have to do with boost levels running the TT setup...not because I'm running EFI...

Some of the stuff I've seen firsthand:

Lifter bores .010" too big
Lifter bores out of position by over .030"
Cam journals too small and also out of round (however they did that!)
"Blind" tapped head bolts actually broken through into the water jacket

Just check everything thoroughly, most of the goofs I have seen or heard about are correctable. Unfortunately some of the stuff (like lifter bore positioning) is much more time consuming/difficult to check and requires the appropriate fixturing unless you have access to a CNC block machining center.

I can ask any number of engine guys I know and they all have their share of "stories" with World Products. Let's not even venture into the assembly tolerances of their crate motors...

The design of the blocks is sound it's just the foundry and machine house have some issues when it comes to changing that design into reality, which is really too bad because the design is good and the price point is right.

For Gen I SBC stuff, iron blocks I like GM Bowtie and Dart, for aluminum I like Brodix.

I was just kidding.... I got the Dart Little M block.......:)
