Both cars and trucks used the 230 in 1966.

Thanks for the reply.It is the original motor ,like i said it was my grandfathers truck .it was passed down to my uncle and from him to me…It has 134000 miles on it ..so the only way to really tell what it is is to tear it down and look at the pistons???Did GM put the 230cid in the trucks in 66 or just the cars??
Thanks again for the help

David,
It could be either a 230 or 250 in 1966 but that was 46 years ago and I would bet it is not the original.
If the pistons are flat top then it is at 230 but if they have a “D” shaped sump, then it is a 250.

The two Carter Weber’s with polished air cleaners look great!

Leslie,
This would be an excellent choice.
You will need an open driveline with about a 3.70 axle ratio to go with the 5 speed overdrive from a 1983 – 1987 S-10 truck (WITH A 2.8L V6 ONLY).

John,
Gas mileage is in the driveline.
Use a T-5 from a 1983 – 1987 S-10 truck with the 2.8L V8 engine ONLY! (.73 overdrive ratio)
Use a 1983 – 1988 S-10 4WD axle with a 3.42 ratio.
Use a G.M. HEI with a soft spring vacuum advance can (1973691)
Use a Holley Weber progressive two barrel on the stock manifold.
You should get 21 MPG @ 65 MPH.

Pat,
Hook up the vacuum advance to the carb per the shop manual.
I suggest you check for a vacuum leak between the manifold and the head.
This is a COMMON problem!

Sam,
Your mechanic is correct about both statements.

Dennis,
You should use the six cylinder bell housing to put the shifter “straight up”
The Camaro Five Speed will need an S-10 (truck) tail housing (and main shaft) for the shifter to clear the front (bench) seat.
