Do some of the small block parts interchange with each other? Intakes could be modified or use spacer plates to work from block to block type? How many types of intakes or heads are available? I deal with mostly big block or HEMI stuff.



Well , R-3 blocks were available with 340 , 360 or small block Ford mains.
In at least three deck heights as shipped and several options from there.
Let's not forget 59 or 48 degree pushrod angles and siamese or standard cylinder arrangement.
Wet or dry sump ?
Not much interchange between W-7 , 8 and 9 stuff...........and I know there were at least two different types of shaft rocker arrangements for the W-9.............probably more for the W-8 depending on who built them.
I learned all that when building one R-3 , W-9 motor.
Get ready for an adventure if you are planning on screwing together motors out of your parts bonanza.
If you're just going to flip the stuff , there is a market , but it helps to know what you have.
