Asking a question to people who run 305's at Knoxville.

How many are going to run there 305 motors next season?

I have two motors that ran almost all of last year at Knoxville. From what I'm hearing these motors are now old news.

Are there two motors out there to replace my two, which will know be in the garage on saturday nights?

I find it to be very entrusting that when a person that actually has cars racing in the 305 class at Knoxville asks what I think is a very important question and yet after 192 looks not one comment.

That tells me that not many car owners or drive are quite sure just what is going to happen and just how it affects them.

I have 2 grandsons racing 305s at Knoxville and can tell you that they are not sure what is going to happen. One drives for a team and who knows what the owner is thinking. My other grandson races on his own dime he is
saying that what he has is what he is going run. If the new rules put him at a disadvantageand he is not competitive he will look else were to race.

I know one kid not racing at Knoxville is not a big deal to them but it is to me.

Most of you know who I am by my log in name. I am proud to say that this season we had 9 kids that have raced at English Creek Speedway participate
in the 305 class. Plus we had 4 young men in the 360s from ECS.

Maybe I am jumping the gun do to the fact Knoxville has not formally announced any rule changes in the 305 class.

I have run 305 but am not right now. I do not think your motors are outdated. The 4 inch bore x 3 inch stroke motors have not proven themself yet. I know of a motor like that a couple years ago and it blew up about 3 nights out. I am no motor expert, but I think the 3 inch stroke motors will have less torque. The 4 inch blocks will unshroud the valves which is good. I would get your. 2 motors ready for next year. The 4 inch chevy blocks oem have been picked thru over the last 30 years and I do not know if they will be any better. Next step is the DART blocks. Like I said I am not an expert.

THANKYOU GUYS . YOUR COMMENTS ARE POSITIVE AND CORRECT...THE OLD 305 MOTOR WILL NOT BE DISADVANTAGED..BUT THE FEW NEW IDEAS WILL HELP KEEP PEOPLE IN THE CLASS AND WE HOPE SUPPLY A LONGER LIFE ENGINE...AND AS.. MARK STATED ...TECHING IS THE KEY TO THE WHOLE NEW SEASON FOR 305

Why would anyone racing 305 sprints want to make any changes . Racesaver rules work and keep the Racing fun and affordable . 305 Blocks ,not 350 blocks ,not Dart Blocks .are you kidding .Don't you take away from the premiss of LOW cost Sprint Car racing .If you want more engine ,go get a 360 .

It's my opinion 305 racing is fun and affordable in Iowa already.

From all I hear the motors cost about the same as racesaver rules.

I just don't want my investment(in a 305 motor) to become $0. If I can't recoup some money from my 305 motor when I decide to sell, it's going to be hard to keep racing.

Hope it all works out, there's no reason it shouldn't.

I heard that 34 is keeping their same rules as this season, I would just like to know so I can start gathering parts up.

$5,000 to $7,000 will put a Legal competitive Racesaver engine together ,What is The Iowa 305 Cost ??? Just curious .

We are going to keep what we have and run it. If (notice I said "if" the rumors are true, there were 2 of the 350/3" stroke motors running there this past season, and 1 of them never got better than 5th place, so "if" the rumor is true about them being there, the old motors will be just fine.

The problem I see with the 350 block deal is you won't be legal at ANY other track in the country. Drysumps were hard to get past most series, 350 blocks are out of the question as far as racing anywhere besides Knoxville or this new series people are talking about. The frequency of tech will also have to be changed if they allow 350 blocks.

Thank you for your thoughts on the 305 situation. You sound alot more positive about our 305 motors then some people are.

I guess I don't see how they will be much different than the old rules. I agree you will get some durability from the 350 block over the 305, and the 350 blocks are a lot easier to find in my area. But as far as running better, I don't think it will be any different than what is already running. If I understand correctly, the short stroke will lose a little torque, 305's are already underpowered so how is losing torque going to make you faster? I just look at it as just because there is a rule change, doesn't mean that those rules are better, there is just another option. Put a normal 305 and a 350/3" stroke side by side on a dyno from the same builder and I will make my official judgement then!! But then again, dyno numbers don't win races....LOL

I thought that there was going to be a meeting for drivers and owners the day of the Knoxville Banquet to decide the motor questions/issues.

Also -- why isn't Ball's name listed for the 305 Owners?

My name was not listed as an owner or driver because I was unable to run 75% of the races this year.

Larry Ball Jr

Sorry Larry Ball Jr.,,,,,I didn't realize you didn't make all the races. That is to bad ...I just wondered why you weren't in the owners points. Good luck next year. Hope Jamie is feeling better.

305 chevy lol. When I was a kid everyone was talking about 305 chevies.... how they wouldn't even smell a 5.0 Mustang. I'm still waiting for a new truly limited, affordable, cheap 265 class.

Luna's Ford engine style that won 2 WoO titles and 3 
Kings Royals before a weight rule against the best EVER
in their prime and now DOMINATES super dirt late model
racing is no longer allowed/wanted in a WoO sprint
car.... Was Luna a miracle worker?
