Best small block book

I have the 340 out of my car. It likes to bend parts for now reason.

I have a guy that said he would check and repair it but he is a Ford guy. I know he will research and is very good at everything he does. What I got to thinking tonight is I need a book for info he might need that isn't in a standard repair manual.

Is there a book you can recommend and the best place to buy it?

Maybe someone here can make some recommendations on the problem

The engine was built about 4 years ago and run on the dyno. It sat for about 1 1/2 years after being built before I got it in the car and running. It is built like the 340 in Mopar Muscle that made 391 HP with 5 mods. I'm thinking it was 2000 when the article can out. Maybe it has been built longer than I 1st thought.

Anyway it has about 3,000 miles on it right now. When it was 1st installed in the car and I tried to drive it the lifters rattled. The builder and I worked on it in the car to try and figure out what was going on. It would sit and idle for 30 min or more and oil pressure would stay steady and no problems. Driving it down the road at a cruising speed it would rattle the lifters after about 1 mile. I got to were I could make it do it just about any time I was driving it. After making some changes the builder and I were out test driving the car and it rattted the lifters but I kept it running and it ended up bending the valves and pushrods in the #5 cylinder.

The owner of the machine shop is the one the tore it down and he told me it had too much clearance in the cam bearings. He reassembled with the new parts needed and when I reinstalled it just never run as I thought it should.

I was planning on having a friend help me tune it to try and get it to run better, but before I did this I was driving on the interstate at close to legal speed so I guess 2,400~2,500 RPM on a warm engine and it rattled quickly and then started to run bad. In checking I found that the #5 exhaust push rod was bent and looks like the valve too.

It is a 71 340 block bored .040, the stock 340 crank turned .010, a seat of "J" heads that had 2.02 / 1.60 valves with hardened seats and bronze guides, the bowls were opened up for the larger valves too.

The cam is a comp cam and about 480 lift 270 deg duration, hydraulic lifters and comp cams adjustable roller tip rockers.

The cam bearings are suppose to have .0025 clearance now.

The 1st guy that built it said the geometry is correct and is curious as to what happened. BUT this guy is really a chevy guy.

I had it built at the machine shop so it could be run on the dyno and I would have NO PROBLEM, was I ever wrong

It engine came out of a 71 Demon........COULD IT BE THAT IT IS POSSESSED?

What should we really be looking for. I'm thinking maybe an over or undersized lifter bore or valve guide that is causing some binding or oil loss.

I think we will install another set of cam bearings and a new cam. Thinking a soild cam or a roller.

What do you think of the Comp Cams roller for a small block?

I'm really sick of this. I could have bought a crate motor, but wanted to have a REAL 340 since I decided not to install the 440 I had. I wish now I had just went ahead and installed the 440 and auto so I could drive the wheels off it with little trouble
