Just had a couple of questions about the 3 Northstar v8's. Tried looking for this information on the search bar but could find nothing.
In The 1996-99 Northstar L37 & LD8 basically the same besides the difference between the camshafts. (internals, head flow, Block strength, Valves & Springs ect).
In The 96-99 L37 4.6l & l47 4.0l Are those basically the same besides the camshafts & that the 4.0l is a smaller bore. (Internals, head flow, Valves & Springs, block strength)
Is It possible to swap the l37 cams & valve springs into the l47 4.0l engine & also would it be possible to put a l37 heads on a l47? Is it possible because of the bores are different.
I've heard that with a L37 cam swap in a l47 4.0L hp will go from factor 250hp to around 320hp?
I just really wanted to know if any of the v8 Northstar parts can be swapped.
And last but not least for the 3.5l lx5 have you guys heard of anything crazy like adding a turbo or sc to it to make more hp or even. Or even bumpin up the compression ratio since its only 9.3:1. Are the internals forged just like the other northstars if anyone has any links to learn more about the internals of the northstar i'd appreciate it.
