Re: Tunnel Ram 4-Speed Bog
Careful with that it allows use of a standard jet, but not a jet extension the notch only clear the jet itself. I liked the idea of turning the carbs around backwards and adding jet extensions to the front (now rear)... I've only dealt with jet extensions on center hung bowls. I use the screw in ty...

Re: Tunnel Ram 4-Speed Bog
You have no way to use a jet extension on it now, most of
them are converted to rear metering block and turned
sideways, then there's no need for jet extensions.
Turn the carbs around and use jet extensions on the primary,
you'll need to revise the throttle linkage.

If you can find two to try, be worth testing.

Re: Tunnel Ram 4-Speed Bog
Are the carbs mounted side ways or regularly, seems to me 660's don't have
secondary metering blocks they have metering plates.
They need to be mounted side ways because of the g force your pulling off
the line, if there mounted regularly your uncovering the metering orifice
or what would be the jet.

Pop a set 5.7 rods in it and mill .125 off piston tops, old 70's - 80's trick to help cost then. Careful to check them 49cc heads for valve clearance on a 350 I wasn't able to get .520 valve lift with out valves striking pistons, if you don't know valves sit at a different angle than stock 23 deg. h...

Re: Running 2 stages of NOS?
Go for it, it'll be fun.
Did that on a '78 Malibu, w/406 mild build back in 1992.
It ran 12.02@ 112mph in the qtr. NA
and 10.88@122mph in the qtr. w/NOS both
kits being hit right at the start.
That was 2 pro/shots kits set on middle setting
I believe it was 125HP or 150HP back then.
