Maybe its a stupid questions...but what exactly is the difference, I have very good knowledge of pushrods but how is a modular different, I know almost nothing about them! Thanks

The modular engine are over head cam and are very wide. Pushrod engines have a cam in the center of the block.

Modular means everything is interchangeable....or something like that. Heads can be swapped, pistons can go in any cyl, I am pretty sure 4.6 heads can be bolted onto a 5.4 block...stuff like that. I think.

Yeah, I know about the overhead cam thing...so bsaically is that the only difference, I know they are alot larger as well..

Exactly what kind of info are you looking for? I am a little confused.

Are you thinking of going modular?

Ford called it modular having the idea of compete interchangability, that plan got tossed out the window. Theres alot of differences in the mod motors from what I have read. They do look great with a carb on them though. Lots of guys running a holley on the mod motors

I just want to know the differences in how they work and things like that. Liek the differences between the 2v 3v and 4v and how each affects performances and the advantages of DOHC over a SOHC and things like that. Maybe one of those moving diagrams to just show how it works... Thanks for the help guys

also things like why, for the most part, modular has replaced pushrods (I know there are still motors out there like the ls1/ls2 and such that still kick ass and are pushrods but I mean in general) Thanks again

GREAT LINK! That really cleared up a lot for me! thanks

and i found this last thought to be really interesting...talk about a power curve "Several engine manufacturers are experimenting with systems that would allow infinite variability in valve timing. For example, imagine that each valve had a solenoid on it that could open and close the valve using computer control rather than relying on a camshaft. With this type of system, you would get maximum engine performance at every RPM. Something to look forward to in the future... " that would be sick!

Seriously though....be careful of that site. You will lose a week before you know it.

One night I stayed up for hours seeing how stupid crap worked. Have you ever spent an hour finding out how a lavalamp works? You will.
