Engine Position-Tech Help Needed

[Patrick]

I have purchased both the S&P LS1 Engine Plates and the Holley LS1 Swap Plates to compare.

Here is what I found: Compared to the S&P Plates, the Holley Plates move the engine back(closer to the firewall) by almost 1.25". However, the Holley Plates RAISE the engine by about 7/16".


So the question is..When building a car for handling what is better:

Engine forward but lower?
or
Engine back but higher?

back, the further the engine is to the centre the better also lower if poss

back, the further the engine is to the centre the better also lower if poss

I agree..however with the plates I have, I dont have the option of back and lower. So given the numbers above, which is the better of the two?

1 1/4" engine setback won't make a damn bit of difference. I would opt for stock longitudinal location and down some.

I would think that 1 1/4 inches would make a difference considering your moving the transmission back the same distance.

You may want to check header clearance before you make a desicion.That was the problem I found.Some mounts aren't real generous with steering box and frame clearance
