305 Engine Source
If anyone is interested I found a great source for a 305 Chevy block. Go to speedwaymotors.com, they have 305 blocks that are fully machined, oven baked and shot peened, magnafluxed, converted to 4 bolt mains, with finish honed mains and .030" over bored cylinders, for $750. The part number is 910-99450.

Is that a Chevy casting, or from Wheeler?

It is a Chevy casting. I am not sure what the shipping cost will be. I have used Speedway for other items and their service is great.

If it's Chevy, it's good. If it is another manufacturer, like Dart, no go.

deck height
Hi folks. Been out a while. Hope to be back one of these days. Catching up on AS reading when I saw this post.
Having been on the not-so-fun end of tech issues I thought I'd point out something about this block and then let people decide for themselves if they want to use it. Jim (Wheeler) brings up a good point about casting numbers, and assuming it is a GM casting then here is another point to consider. I believe the current rules say that the GM block deck height has to be 9.007"-9.043". The Speedway block comes in just under that at 9.005". From the Speedway site under this block part number (91099450), Questions/Answers, Question #2: Q: What is the deck height? Asked on 11/14/2011 5:38:32 AM by from NY Answers (1) Know the answer? Answer this question A: This block has a deck height of 9.005" Answered on 11/14/2011 8:59:57 AM by Jason from Speedway I'm not sure how anyone in tech would measure this, but do you really want to find out?

Damn, the devil is in the details. That being said, we changed the first gear ratio rule to allow a very good transmission into AS in view of the problems with Richmond Gears (now gone). I think something like this should be considered, given the fact that this would save a ton of money over trying to find a good, unmolested, block on which to spend a bunch of money for this level of prep.
Good catch, Bill. Are you going to race this year? wheel

no engine $$$
I wish I was going to be able to race this year but I currently can not afford to build a competitive AS engine. Maybe next year....
May I ask which transmission was allowed in due to the 1st gear ratio rule change? Thanks.

The first gear on the Muncie were just barely outside the + or - rule. All the other gears were within spec. This comes from AutoGear and has the good Italian gears. By the way, I understand that Richmond is gone (bankrupt or just shut down, I'm not sure) and there will be no more new parts for the T-10. I may not have all the details correct. Pam knows a lot more about this than I do.

Richmond
Rumors (unconfirmed) that Richmond, purchased by another company, has stopped selling T10 parts. I have no idea yea or nay, because I haven't tried to buy T10 parts.
If anyone else has any intel on this, please pass it along! Pam

They were purchased by Motive Gear, There is no word if they are going to continue the T10 line. I believe they are looking at somethine new to replace the T10. That is what is going around the grape vine.
