LD340 v Airgap

raymond said

Thanks for the reply, my LD has the TQ mods plus when I got hold of it the WHOLE divider had been removed along with just about everything else in the plenum, it's not a pretty sight, I'm thinking the mods haven't helped it. Its in a 68 Dart has around 10.8 or 9 comp Eddies at mid 280's hyd / roller 222@.050" 1.6 rockers 999trans and 3.5 gear, It's gone 11.50 in really good air, it could probably use some more cam but I'm old and grumpy and more cam will drive me crazy. I'm thinking if there might be a bit in the AIRGAP for me I might grab one.

I had a very similar street combo, except with a manual trans.The cam was a Hughes 223/230/110, and the intake was an AG. I loved that combo; gobs of low-rpm torque, a solid midrange and adequate top-end.
When that cam died, I installed a Hughes 230/237/110 and bumped the DCR back up to, maintain 180psi .
The engine got a whole new personality.
I went to the track just one time, and she pulled 93mph in the Eighth, at 3650pounds/900ft elev.

I liked the first cam better. it had a significantly stronger low-rpm torque, that a manual-trans car really needs. The top-end was not as strong, but in a streeter with 3.55s that was not a big deal. IMO it was Not a good swap. I have been waiting since 2004 for that 230 cam to lose lobes, so I can go back, lol.
