When going to a 30# heaver steel block do you need to raise the motor ?
The typical answer you going to get is if a steel block: Move up 1" and to the right. However this is totally NOT a 100% rule but a lot of the time it is correct.Quote:

Our open engine and our Steel block spec engine have the exact same COG so the engine does not need to be raised but you do have to compensate for the slight weight difference by moving slightly right to keep the LS% the same and add a touch of lead to the back of the car to keep the rear % the same.
To make a blank statement that if a steel block engine it goes here, is completely a guess if you don't figure the COG's of the engines your comparing too. I still have yet to find a non professional team that has ever been able to tell me that, without having them do it first cause I told them to figure it.
If you're comparing similar CID and stroke engines but just a steel vs alum block the 1" up and right is generally correct but comparing a 430 alum and a short stroke 32# crank honda rodded 360 to 380 steel block is completely different.
Thanks for the reply .We went from a steel ford svo block to a dart block with the same crank and stuff was just wondering .
How about if a guy uses a all iron motor?
In that case, there is a lot of weight on top of the engine, so you'll likely keep it low, but you will want to get it to the right or you will be VERY LF heavy on the scales.
Thanks for the response.
