best v8 block for buildup
Hey guys,
I think I want to start building a new motor for my car. I want a good amount of power out of a 350 block (400rwhp).. Decent gas mileage is a must.(Sounds hard with all the power) What block is the best to start with? Is my stock 84 block ok, or should i go for something else? Two bolt/four bolt mains, one an two piece rear main seals.. Input would be great.. Thanks guys..
My opinion would be to start with a roller block from a tune port vette, 1 piece rear main, and four bolt mains.. Is this the right direction, or am i off completely..
:cheers:

Re: best v8 block for buildup (atotalnincompoop)
If you're looking for something that requires less maintenance, then you're thinking along the correct track of a 4-bolt main roller block w/ 1 piece real seal. To my knowledge, the strongest of the mass-produced blocks (meaning non-Bowtie or Rocket block) is the '87-up 350 4-bolt truck blocks. The Callaway twin turbos were upgraded to these blocks when Callaway did the conversion. Basically they have more beef in the webbing around the mains. However, if you're only looking to make 400 rwhp, the Corvette block is fine.

Re: best v8 block for buildup (quiksilver458)
The BEST block? Part of the answer depends on your definition of BEST. You could go through the various catalogs and racing books and find the most expensive block available. You get what you pay for? A "Little M" or Bow Tie for $1800.00 to $2000.00 would be great. A $4000.00 aluminum block might be twice as good. However, for a 400 rwhp engine, your 1984 block will do just fine. ANYTHING can be over done. Good luck, and...

Id use a 4-bolt block with a 1piece rear seal, ZZ4.
If you want that much power, you should look into getting ARP splayed main bolts.

In my 84 I am going with a 91' 4bolt main 1pc seal roller block out of an Ambulence (350ci) you can see my post at the CFI Forum here: http://www.crossfire.homeip.net:81/c...e+and+Upgrades
Take a look at that for my engine It is projected to put about 397hp to the rear wheels. :cheers:
