He stated final decision on 12/1 Lonnie so whatever would bring the car count up needs to be considered. Not knowing much about those engines and you saying 3550 is a good starting point then so be it.
If the rules are not written I will plead the case. 3800 Series 2 and 3 are improved versions of the 109 engine. For those who do not know were installed in most GM FWD cars in 1995 threw 2008. My observation is as follows. The block is hi nickle with 4 Bolt Mains and steel main caps. The oiling system is improved as is the cooling system. The Heads are symmetrical and come with larger valves than the 8445 heads. The heads more than likely flow better than an average ported iron not even close to ported aluminum. There are no aftermarket cranks so the stock cast 3.400 crank will need to be used bringing the CID to a whopping 234" The intake is restricted to FWD or F-body cast intake. (Since sheet aluminum would not be allowed) The heads bolts are 4 per cylinder 12mm slightly Larger than 109. Not 6 per cylinder like a stage engine. The short block is stronger than 109 but not as strong as stage. I agree and understand the 109 needs to get any break that is available. I also believe this little engine could be a viable option to the Buick Performance community in the near future. I do believe the strength of the block and possibly the improved cylinder heads that weight should be added. I think a fair weight should be 109 aluminum weight. The 3800 does not have the CID capability of the 109 or the head flow capability of the LC2 Aluminum Heads. Since I feel performance wise its in between iron 109 and aluminum 109 I would think aluminum weights would be a good starting point. If we know that weights will be adjusted for fairness I would think there is more if a case to start at the lower weight and add from there. I would like to say that the 3800 rule would bring in more cars but I am sure thats not the case. I only know of 3 running cars with them and I think I am the only one that is looking to run at this level.
