Yes, I've been thinking about that, but should the pressure really be so high at the filter then? My friend who built the engine sadly passed away in November so I can't ask him. That's one of the reasons the project was put on hold.

OK, time for an update: I replaced the 318 with a 302 LS1 big block Poly engine and now I'm hauling Caterpillars through Ukraine. No. I was wrenching all that last night to have it running for that one day at the track. Weather was cold with showers. I made one pass on cold slippery asphalt...

We’ll see if it works

Wtf? Been shifting between different mounts but couldn’t find a perfect fit. Finally got it in there. Thought it was okay until now. Been working with big blocks and never experienced this. Now what? Tranny and engine together and everything else in place, only thing left for start is flexplate...

That's pretty impressive. Auto or manual? What cam and intake? At what rpm did it peak?

Thanks for your input! I know it would be better with a higher CR but I didn't want to mill the heads since I don't know if I will sell the 318 or putting it in something else with another cam. I will check the cylinder pressure when I get it running just for fun. My cam is installed at zero...

I had to make a choice yesterday and I used the B&M. I picked it because it's smaller and would give a higher stall speed.

I have two converters: 1. Hughes #24-35 2. The one in pictures. Does anyone know what it is?

I had a hassle last night to get the valve train in the ballpark. Couldn't find pushrods short enough so I had to shim the rocker shaft 1/64 to make it work. It's not optimal but it should work. We'll see!

I got the 318 short block already put together. It was seriously built buy a racer I know very well and I got it dirt cheap and was intended to go into my Warlock. If I would have to start from scratch I would probably do like you described but I have been very busy and want the car running for...

I was going to build a 377 of a 340 block I have, but couldn't find any this spring so I took what I have to get the car running so I can sort details out for next season. Plan is to build a mild and reliable mid to high 6's car for Swedish Street Week. The 377 will have a mech cam and tunnel...

Don't have a chance for dyno time this time of year. Will take it to the strip August 1st though :)

PM me!

Looking for a high rise tunnel ram for my nostalgica 340 Duster build. PM please

Exactly. All the pistons are higher on "right side" then on "left side". If the block would be off square piston #7 would be an inch above deck. There was some carbon build up on the top when I took the pic and that's why you can see some light under the straight edge. I cleaned it later and...

When both valves are closed no air is moving. There was even a pinch of rust resting in the exhaust port. Took the valves out and everything looks fine.

Yes they are all like that, and Yes it would be totally impossible to make that in an lathe - but it would be possible to mill them off square

Hi everybody, Got myself a 71 Duster a couple of years ago, seller had no clue of engine internals or nothing else but I got a good deal and bought it. Haven't had time for it until now. 340", Eddie heads, Torker intake, expensive red dp carb, newer crap MP distributor, Hooker Comp headers...

Really interesting! And like he says in the end, you never know until you have tested :)

Seems like you still are a little closer than me! LOL I will do as you say, ask some good cam grinder and follow the recommendations. I know pretty every detail except for the exact weight, but that we can estimate

Yup, that's another cam in that range. Question is if it's grind with .904 lifters in mind or just another Chevy profile?

It would be sooo interesting to hear your opinions after your test run! With that narrow LSA it should make a lot of power from the bottom. I'm sure you will get tears in your eyes if you're behind LOL

I went from RPM to the lower Performer, shaved off the J heads and put on a smaller 600 carb on a 360 that came in a Cuda I bought and it really woke her up. It had an unknown cam but it was kinda hot for a street car. I shaved off a little too much so it got 180-195 psi cyl pressure. I had a...

It's very easy to over cam any engine. And for this engine I really want to find the cam that really makes it shine. not too big and not too small and that's why I ask for advice from you experienced people.

I have spent time on those links. The thing is that in both tests, especially the second, use a lot bigger cams.

Good and useful information, thanks! Don't you sacrifice some of the low end power and response and with a RPM intake?

Please explicate :)

Since I'm in Sweden there's a time difference, and I was busy last night. Been looking at the cam(s) you recommended but they look rather small in both duration and lift? The LS on both Elgin and Crane are 112-114 which I think is a little high?

Just changed my mind, it will get headers.
