My first post I was only telling the OP what I learned the hard way. The heavier it is the more power you need to go fast. My car went 10.00's It was an all original street car I ran through the exhaust . The spare was even in the car as required to hold the factory tank from ripping the floor out. I even had the trunk mat in the car. and the floor mount cassette player. They are usually 3000 - 3200 lbs. My car weighed 3650 with the mild steel cage.
You have to spend a lot more money on the drive line to make up for that weight. More than the cost of a lighter cage. I didn't tell the OP anything else . But As usual yellowrose and others know everything there is to know and every one else is a jackass. There is new technology and if you don't accept that in life, It will pass you by. I know I am a recipient .
Most of you know I am not a machinist. My son is, And builds some pretty radical motors. What I know I learn from him . He has been doing this for over 11 years at a well know Machine shop and has his own new machines in our garage behind our house. There is nothing he cannot do including welding up motors and heads. There is a long line just to get him to do work. He is friends with several racers and does machine work for a NASCAR race shop.
"I can deck a block faster than you" Big deal your **** is still cave man style compared to the finish of these new cutters
Remember there are three words of wisdom when taking a motor to a machine shop.
Fast , Cheap , and Good
1. Fast and Good are not Cheap
2. Cheap and Fast are not Good
3. Good and Cheap are not Fast
As far as oiling mods , I did post some of them. If you want more come pay to get a motor done and he will teach you. He is just finishing up last years points champion. SBChevy Dart race motor. He chased me and the dog out of the garage. He said we were causing dust. He sold that new machine he bought. They picked it up Friday . He bought another one and is buying a new Balancer.
Those of you that live near can stop in when ever. My address is well known. Social media "SK Machine" My son is 34 a big guy 6'4" 230 lbs been racing since he was 13. He is a well mannered person and will work with anyone on any type of build on their budget. Until someone becomes an A$$. He does not have much of an overhead every machine and tool here is paid for.
Street bikes, Harleys, Drag race motors, sprint cars 358's and 410's. Nitro , methanol, Diesel, Modified Nascar. Roll cages . Chassis work. The list goes on. There are members that come here just to watch some of the things he knows how to do.
I don't have a clue on things he knows. Some of the tools I didn't even know existed. I taught him Mopars . The rest he learned in schools and on the job. He draws things on the computer in minutes and sends it to the plasma-cam. I wouldn't even know how to enter the program.
My job is to watch the cutter and make sure the pieces fall out so they don't get caught. I am also in-charge of cleaning up the metal chips and driving the dog and grandsons around on the Golf cart. Otherwise they are in the garage asking the two famous questions. Whats That? and Why?
