Roush 427 SR verses R

[FredG]

I keep the idle a tad higher and just need to use a few more rpms to get it going. After that, it's fine and you can drive it anywhere. If I wanted something that was more streetable, I would have bought an automatic Vette or put in one of those Iconic things. You should probably try to drive one.

I would like to try the R but my concern with the R is off the line from a stop light...will it bog or do the jerky bounce? From a stop making a turn, will it stall until the torque curve kicks in? And can I take it on a 200 + mile cruise without issues?

Any videos on the R off the the line in street driving?

SR has dual plane manifold (street/torque oriented) vs single plane on R (more WOT/high HP oriented). The car is so light, you can really go either way.
I have the Craft equivalent of the R with a Performer RPM Air Gap. I ended up switching to an EFI ($1200 system) to tune around the low vacuum, which the carb didn't like below 1800 RPM. If you choose to go this way, let the engine builder know and ensure they use an EFI friendly camshaft.
