IF! And that is a HUGE IF anyone had the FU money to even think about doing another pontiac block I see NO need for a short deck!I think I have built more off the wall pontiac engines.3 short deck block,dont know how many RA V iron engines,two FACTORY alu block from 2 diff generations and you have not a snowballs chance in hell of getting any ROI on building it.We drag racers have it hard but nowhere near as hard as someone trying to road race a pontiac with a pontiac.Im doing a 455 for mine as my 366 NASCAR V engine would be a dog and WAY to valuable to take a chance on breaking.Tom

According to Frank Gostyla, the 9.5-inch short deck IA2 can be milled to the 9.225 inches, which puts it on the list for consideration. It would need to be sleeved down but would otherwise be usable as is. In addition to being very beefy, they also offer the option of running a smaller-diameter 2.75-inch LS main journal with an aftermarket spacer. The only real disadvantage is that it isn't the lightest alternative available and may not be allowed in certain vintage classes requiring a factory block.

I haven't spoken to Frank or Bob about that but they are both very sharp guys and I am willing to bet that they have researched the topic.

I know that Dart offers optional CGI casting with most of their higher end blocks.

He built anew. His closest in-classcompetitor was a 70 Z-28 SBC 4-Speed that spun very high hi-rpm by comparison, and they took turns with 1st place. So that convined me that the 455-TH400 was a competitive road racer, butt hey itsa heavy compared to 4-cyls econoboxes and the Exotics. |

It's not all about weight,it's about weight bias. Can't remove weight from the front end? Move everything you can to the rear end of the car to get closer to that 50/50 balance!

What does it cost over there for a sleeve,$100 a bore? $800 doesn't seem bad to me.

I recently(last month) paid about $120 US per cylinder including the sleeve itself.

$120 per sleeve is a good price; the problem is finding a COMPETENT machinist to install then without turning the block into a worthless boat anchor.

Most machinist tell me its not a good idea to do all 8 sleeves as it can compromise the strength and integrity of the block.The only block I have ever done that to was a early pontiac 389 alu block that was intended to be run like a Vega with no sleeves.We used 350 60 over thinwall steel sleeves in it.Tom

8 Nicasil Aluminum Sleeves in the V8 for reduced weight and performance....now THAT would be amazing.

HIS,Fritz told me they even tried hard anodizing the bores to keep from putting sleeves in those early alu blocks.Tom

There is a point that moving weight from front to the rear causes handling problems and negates the good it does. In a drag car it's not as important to keep the weight between the axles and as low as possible. |

Brad,
Yeap, is why my battery is mounted on the trunk shelf above the rear. Been opining about moving the battery close to the rear bumper to promote bigger wheelstands, but i do drive the car on Streets way more than the 1/4.
