73119, Long rod Vs. Std. rod size Posted by titogs95, Apr-18-04 07:20 PM
What's up?!!! This is the deal.
My car has around 125,000 miles and I want to rebuild the engine.
I do not want to go turbo and I will like to get all the potential juice that I can out the little 420A.
While; I was researching to rebuild the bottom end in Howell, I saw this short block for sale. (http://www.howellautomotive.com/How...Path=142_38_192)
QUESTIONS:
What is the difference between the block that has long rod and the other one? (obvious is the rod but what else is what i meant) What are the pros and cons? Is the long rod going to hit the head? Do they use the same piston? Is the compression going to be higher?
About the pistons what is that number .20 (BORE SIZE) What is that for? Is .030 inch better or .040 inch??? In what that is going to help me?
I am planning to go high compression and maybe stroke to 2.2L. BTW the top head of the car was melt.
So, please help me about it.
Any opinion about rebuild or other stuffs are welcome.
Thanks in advance. Tito.

A long rod block will give you a little extra torque due to the rod length. It shouldn't hit the head. They have to use specially made pistons just for the long rods, so the compression ratio you order is what you get. The bore size is how much over the standard bore you want, in inches. When you take your block to the machine shop, they will take away some metal in the cylinders to get them back to true. When they take away metal from the cylinders, it needs to be filled with slightly larger pistons. It isn't going to give a performance gain either way, but you may want to get your block checked before you order pistons, so you know how much they need to bore it out, and you can order the correct size.

Thanks for the info. I think it will be a challenge be driving with a lot of torque in a front wheel drive car.
learning something else is always good, (staying away from the old routine).
thanks TITO

I think you'll find that the long rod gives minimal gains over the stock rods. If you plan to rebuild with a 2.0l, then buy the long rod engine (its only $0-100 more). If you want more sizeable gains, I'd opt for the 2.2l. Its alot of money, but it will give very respectable gains over the 2.0l. I'm doing a rebuild right now and was too cheap to get the 2.2l. So, I was stuck with a 2.0l. The long rod kit was on sale for the same price as the standard kit, so I bought it. It will give some gains, but not like the 2.2l.

Thanks that was one of the answers that I was looking for!!!
I am thinking now to get 2.2L stroke, high compression and a little bottle of NOS.
I appreciated and hopefully this summer my dream is going to come true. (Damn I have to work a lot and do a lot of extra shit to get some $!!!)
More suggestion or comments are welcome. TITO.

hey, read this...you might get an idea as to why longer rods give you more torque
