I have a 408 stroker in the works. I went with a re-ground cam. Saves cash at around $150 plus shipping vs $350 for new, plus I can reuse my distributor gear. Here are the specs from Ken at Oregon Cam Grinders #1357 230/236 @ .050”, 284/290 adc, .515”/.515” lift (1.6:1 rocker), 108 sep As you...

From another thread, I asked how the machine shop decides on a piston. We've determined I need somewhere in the 23 to 25 cc dish to arrive at 9.5 to 10:1 compression on a 408 stroker. He wants pistons there before boring to 0.30 over. Got this reply and I understand it except how is deck height...

This is kind of a sticking point in planning this build. Szilagyi in "How to Build Big inch..." states that the stock Magnum rockers are good to about .0525" lift. I don't really see the need to go bigger. My non-ported RHS heads don't flow better above 0.500" lift. And I'm building a street...

In my research for building a 5.9 into a 408 stroker, I read that the 340 is a preferred production engine for a stroker build due to its large bore and thick walls that can take a .040 overbore to make a 418 stroker. This reference (How to Build Big-Inch Mopar Small Blocks) suggests that...

My project keeps changing. After being mothballed for a few years, I've gone from planning a "junkyard magnum" to doing a stroker. For those who want to see more detail on the project it is here with a post titled "The Frog Wants to be Stroked": Project Frog Princess I have RHS heads from IMM...

Just looking over my old but just unboxed heads, noting some variance in valve tip heights. Can anyone help with what is an acceptable variance?

Found this on a Ford forum. Wondering if this will work for the lifters in a 5.9 Magnum. Images did not copy. Here's the link: http://sbftech.com/index.php?topic=57.0

I've been planning a junkyard 5.9 Magnum in my 69 Dart, with plans to use the RHS heads from IMM. I'm close to ordering heads and find that for whatever reason, I'm wanting the Edelbrock Performer RPMs. One reason that makes some sense is weight reduction. I've added about 50 lb with Caddy...

I've settled on using RHS X heads on my 5.9 Magnum build. I've read stories of the assembly of the heads being poorly done. It would be nice to have a good local shop do the work. I thought of using my 10% Summit discount for the bare heads but not sure who to trust. Also thinking of what...

I have a '73 340 needing rebuild for my Demon clone project but am considering all options. It's intended for weekend street fun, maybe occaisonal 1/4 mile runs. I ran across this article: http://www.hotrod.com/techarticles/engine/hrdp_0804_small_block_mopar_engine/viewall.html Here's a...

I'm planning a restoration on a 73 Duster 340 4 spd for street use. The 340 will need a rebuild and I'd like to achieve a 13.0 1/4 mile time. It will likely weigh the typical factory 3300 lb or so. The rear tires will have to fit in the factory fenders. I expect to have to replace or re-arc the...
