What's your plan for cams and exhaust? A pair of performer grind cams would drag a barn at 750 RPM! Quad exhaust or an 8 into 1 into 4" exhaust tubing? Or?

funny you should mention that. I have one Edelbrock in the motor that was in the RV
and just ordered another. 448 and 472 and 214 and 224 at .050. exhaust will be free flow manifolds with 2.5" duals.

Kenz and Leslie joined flat head Fords in the V-16 manner
back in the 1940's and 1950's.

They ran three Flatties in a stream liner on the salt flats.

Properly balanced it should work well and be reliable.

Twin engine applications are nothing new.  In addition to those mentioned, the 'Freight Train' dragster was one I always think of for twin engine combinations.

I am still skeptical about long term crankshaft strength (and life) in this application.  I don't know of any example that was intended to be good for 50,000-100,000 mile of dependable, fault free service.  But so what, you want to give it a shot, go for it. Thumbs Up

A transmission change and/or rear end change (2 speed) for a wider gear spread to get going and stay going would seem to be a simpler and more efficient option ... or add a small turbocharger or supercharger if you really need more torque/hp.

Ya that's the main reason. My single 360 pulled fine just had to be patient leaving the giant crater we live in. I could skoot along just fine at 65 mph pulling my Rambler in my trailer.

Ok The Land Speed records classes the AMC version of the Spirit of America would have run in were displacement limited , so no two AMC V-8 hooked together. One AMC V-8 with a GMC blower was what was planned. I did a lot of research the History of AMC Motor Sports for Bob McClure on a lot of this stuff. Also NHRA outlawed dual engine drag cars circa 1972. Yes there was a dual six cylinder engine dragster and then the team went to a six cylinder Gremlin . That is in the Performance American Style manual AMC put out in 1972. No one ran a dual engine car after 1971 except in the nostalgia drag races and then mostly for show.   LRDaum
