I'll prob-lee get flamed for this bc of it being a truck motor, and asking this ?, but is there any reason an 2001 LQ4 won't fit in a V1? I know its iron, and it's lower compression, but is there any reason it won't bolt in. Then if it would bolt in, couldn't you use the LS6 top end and a custom cam and have a pretty stout set up?

just curious but what would be your reasoning for using an LQ4 instead of a LS2 or LS3?

Well, mainly bc I have one, and bc I thought that LS2s and 3s have a different crankshaft ring for the crank sensor to read. I don't know for sure about the latter, or if there is a simple fix to it either.

The only way I'm going to approve of this is if you're running high boost levels to it.

4.8, 5.3, 5.7, 6.0, 6.2, 7.0, etc will all fit the same. An LS block is an LS block as long as its for a rwd app.

Umm double check the dates. The crank changes right around then. The early lq4s have a different crank. The latter ones have a normal crank with a spacer for the flexplate and transmission. The early ones will not bolt up to a 6 speed correctly.

Thanks all for the replies. Didn't know if they would be any problems. I had heard that iron truck blocks didn't have all the accessory bolt holes like alm. car blocks have.

Only bolt hole sometimes missing is one of the alternator holes. Real easy to drill/tap it though. It is on the edge of the block nowhere near oil or water.

Thanks for the reply. So drilling and tapping one bolt hole should be the only non bolt on? The LS6 top end should be a direct bolt on too, I hope.
