I asked this question because there is a Mopar Performance wedge block on here for sale. Since hemi blocks are obscene at the moment, my friend who does not do moparts had the idea that the wedge block and stage v stuff would make a good combination.

I think a good set of B1 or a set of B1-MC heads on a good wedge block will out perform and out run a hemi conversion set up twocents work

I agree 100%, but some people just WANT a hemi. I was all set to build a B1 engine before I found a real good deal on a hemi top end package. Glad I did, b/c I really just wanted to have a hemi...even knowing a B1 combo like mine will likely be faster.

My engine builder did one a while back. It makes good horse power, and if the block is cheap enough and in good shape, its probably worth it. What is nice now a days that people don't mention is the proliferation of stroker kits, AND the lower end girdles kits.....This I think makes it worth while investment, with the right engine builder. I say that because if I remember right, You have to drill out and re-tap the head deck holes to a larger size. Plus the girdle can be a pain to setup, and getting the right length head bolts/studs can be a pain too. Its all time consuming. More so with all the little oddities this combo brings.

And even if you built a wedge as suggested, everone has one, and they suffer from the same HP limits as the Hemi and need a girdle.

Heck even one of the big magazines built one, and it made 680hp in a street car if I remember......We saw one at the drags last year making passes. I do not recall what it ran. Looks almost like a regular Hemi unless you really are looking at it.

For somthing to tool around town in, and enjoy, I would do it. Hemis are damn cool. The girdle will really help along with a rev limiter. Don't look for Mopar to save you by bringing anything back.

I always wanted to do one of these in a low deck....I here FHO was tooling up to do a low deck, so if he comes out with an intake, man that would be cool...A 400/512 stroker low deck Hemi!

I thought about the low deck 512 hemi conversion for a NSS 68 Barracuda but then spent my money on NHRA D/S 340 6pack which is still in progress. I think the Hemi would have been cheaper.

iagree

Personally the wedge setup just makes more sense unless you simply want the look of a Hemi. twocents


Kayse can't keep up at all now. lol

Its still on my bucket list to do one. I have a 75' 400 block to use. I think short fill with aluminum main caps on a good block would last a good while on the street. I do street/strip and shows. The Hemi gets a lot of attention at the shows.
