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 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.
