dave, i run a 528/294 camshaft
did you mean what size is my exhaust system or exhaust valves? im not sure because you asked about my cam...so..

my exhaust is comprised of 1 7/8 inch flowtech headers into a 4 inch collectors through 4 inch mufflers...with 4 inch outs...into pre-diff. outs....obviously all custom made of stainless because as im sure you can imagine, such as odd car doesnt have anyone making exhaust systems for it.

my exhaust valves are 1.67 with 1.88 intake valves, but we currently have a set of 340 J-heads being cut for 2.02 intake valves.

 

Only 1.88 intake, man, I didn't relise they were that small! Are the new head 2.02/1.68? If so, I bet you see alot outa that cam, she'll finaly be able to breath.

 

Great thread!! Some of you had some really nice first cars.

My 1st car was a 1971 Dodge Colt. It was actually a Mistu but Dodge imported it. I bought it bofore I could drive and did all the bodywork and paint on it.

About 8 months after I got it on the road I blew up the engine. A kid in my school had a brand new Camaro when they went to the F-body for the first time. His car was a 4 cylinder and Auto. I challanged him to a race in my 15 y/o car. I won!! He was pissed. 2 weeks later my engine blew. I guess he won.....

Then I got a 1967 Mustang to replace the Colt. It was the best car inthe world for a 17-18 year old to own. I beat the crap out of that car and it NEVER complained. I wish I still had it..

 

my new heads are 202/167, and will be ported and polished...188s are the stock size intake for the 340, although they are 360 heads..

 

I wish I still had my first car today, because I'd be stupid to beat up my audi the way I treated that car. Damn, good times

 

The stock intake valve size for the 340 is 202. That's what's in my 68 340 "x" head has. I think all 340's from 67 through at least 69 came with 202 intake valves and an "x" head casting. iirc.

 

i dont have X heads...i WISH i had X heads...the 340s came with U, J, X, and something else which illudes me at the moment...X heads were the best due to the valve size and port size/quality...i believe that the heads that i am having done are U heads..which were the worst of them,.but i got them very cheap...like i said..my car is being stored some 400 miles away....in a agrage full of parts....i have tons of heads, none of the hipo...and although my 360sp heads are ported and polished, they are still only 1.88s...my 340 block is a 69, but when i bought it, i didnt get heads with it...my block was a Steal from a moron who didnt know what he had...250 bucks with the crank and and rods..no pistons no caps...with a 727 tranny and the factory 69 cuda AC parts...which were sold immeadiately...
