    firing order help - please pardon my ignorance

    Chill - Give yourself a break here! Firing up a new engine can be quite stressful - there's a lot at stake and most of us don't have the coins to repeatedly go through the process due to simple human error. Take your time, get it right, and enjoy the fruits of your labor. Keep us posted and...

    Comp XE268 - O/T, Brand X!

    I have a couple of buddies that run Tin Indians and I can tell you without equivocation that this is a factual statement - intended or not...! LOL In all seriousness though, I run a XE268H in the 390 in the wife's Swinger; can't say enough good things about that camshaft for usage in a true...

    Edelbrock RPM Head compatability issues.

    The 60179 heads have slightly larger chambers - and were introduced because Edelbrock failed to anticipate how many guys were out there still running factory pistons that protruded slightly above the deck and this created some clearance issues on the original offerings which were P/N 6077 -...

    What Pushrod To Use?

    Smith Brothers makes some really good adjustable pushrods too...you could order an adjustable set and then fine tune each one... Just another option, but you'll still have to give them some initial direction on the desired length in order for them to build them. Ray

    Anyone confirm that the Lunati VooDoo cams are .904 lobe width?

    I read that thread on the VooDoo cams a couple of months ago when it was first posted and immediately wished I had gotten one of those when I built a new 340 for my '74 Duster last year; instead I had opted for the Comp XE268H. It's been fine, but it sure sounds like I left a few ponies on the...

    340 Steel Crank Questions

    I have also heard before that due to the designed reverse rotation you cannot adapt a marine crank to an automotive application. The serrations on the crank mating surface for the rear main seal are machined in the wrong direction and will force oil out rather than away from the seal if run...

    putting the motor back together

    I think your best bet for this first engine build is to find an engine building friend that lives near you. Someone on this site with experience must live in close proximity to you. There is no substitue for experience, even if you can & do read & follow the instructions in an engine assembly...

    273 rocker help

    I agree with Walt; if they're cheap - then buy them. Just put them on the shelf for now if you choose not to use them. Some project will come up some day that you'll want them for... I ran 273 rockers on a 340 with the old .572/296 Solid Purple Shaft back in the eighties. Never had a...

    Cam breakin Procedure

    One thought that no one has touched upon, and for good reason as none of us like to have to go through this, but that is to use a set of break-in springs for initial fire-up. I did this at the behest of my machinist (who has seen far too many cams wiped out recently, even by people that know...
