Looks mighty cool!

I´m currently putting together the heads, and have a question (shocker, huh?)
Can I use the valve springs in my 273 for the new 340 cam?
Might sound stupid, but this is actually my first enginebuild.
Input please. :)
 
Oh yeah, could´nt brace myself the other day.
Heads are empty, just had to hang it together to see what it would look like.

Looks great, actually if you wanted to boost it you could, turbos are not as hard on components as a lot of people think cause its a gradual increase in power as boost builds its not shocking the internals like nos does. If you kept boost low like 5-10 the motor would do just fine. Just my .02

It should be a safe way to break in the new cam if it's a solid lifter. either way I've done it until I could afford better ones.(one set was so weak the valves would float at 5 grand.cheap rev limiter) ;D
double check for spring bind w/new cam.
Have fun
 
Your engine really looks good! Im just talking here is all but reading what Matt said about the turbo, i learned a little and it would be cool to see just what a turbo on the 273 would do, i have one out of a 67 Coronet with 80,000 miles on it and thought of rebuilding it (when $ situation gets better) and trying to get some extra HP on it without going to big extremes, kind of curious how much you actually could gain! Would be interesting... Good luck with this, if she boots and scoots the way it looks, ya have it made!

Well if you look at some of the kits for now a day cars at just like 8 psi they are going from stock and gaining 150+hp. But you can go either single or twin turbo. Now if your gonna rebuild just get a steel crank and forged rods and pistons, run any where from 8:1 to 9-10:1 compression, just higher the comp the lower the boost you have to run, a lot of people go with a single turbo. Some are getting 600 out of stock bottom ends too. If your interested check out turboforums.com and look under the mopar section and check out some builds that are going on. Plus there are a few on here that have turbo mopars.
 
I will check that site out, I cant do anything with that now, but options are always good to have. Thanks..
 
Checked out the turbosites, and man!
Looks kind of cool with a turbo under the hood.

Nothing for me, but still damn cool! :icon_mrgreen:
 
Ooh man, She do sound good! you get it dialed in that will do it!!! Im sorry, couldn't understand a word on the radio in the back ground though.. :)
 
I hope that 273 runs good for you. I would suggest a 3.23 gear with that 3.31stroke crankshaft.
