Question about a Type III engine. How hard is it to change a single port motor to a dual port motor? Cost wise what would I be looking at? To go up to a 1776cc motor.

The car has a 1600 single port with dual Solex carbs. There is a module in the distributor to replace the points, but I don't remember which brand

New heads and P&C's to make it a 1776, and dual port manifolds and possibly new carbs.

= ching ching.

And have the block cut for the 90.5 cyl

Right on.

Don't forget about the cylnder tin

The cylinder tin can be cut and trimed to work with a dual port application. Basic run down on parts: $500 for a pair of heads, $500-$800 for carbs, with limited choices(T3) another $300ish for P&C's, and $150ish for machining the case. After machining the case you need to rebuild it with new bearings etc......might as well put in a cam while its apart.......You are basically building a new motor. My recomendation, build a 1641. that will only cost you $200. I drive the shit out of mine. And I drive it on the freeway! What kinda car are you looking at? With a T3 you need to be picky about it. Parts are a P.I.T.A. to get sometimes....Ask Chuck. He owns stock in ISPWest!

gotta have the heads cut too
