Hmm, Is there any internal differences between the TH350 and the TH400?? The lump and tranny have never been touched they are as they left the chevy factory over 40 years ago even on the original plugs and leads! Also how can i tell if the box is a TH as its fitted and cant see much?? Cheers!

On the block, the casting number is on the narrow little ledge, driver's side, where the bellhousing bolts up and there is also a stamped suffix number on the passenger side block deck at the very front of the block just in front of the cylinder head. On the heads, the casting number is on the top of the head, under the valve cover, between the rocker studs.

A gasser would be a coupe or sedan body with any motor, streetable with fenders, bumpers, full interior, etc and with the motor set back in the wheelbase a maximum of 10% as measured from the centerline of the front spindle to the nearest spark plug hole. This was a popular class 50's to 80's, but has been taken out of the NHRA Rulebook. The gassers running these days are nostalgia cars running on different circuits (different sanctioning body from NHRA).

A fueler is a car that runs on pure nitromethane or a percentage of nitromethane, cut with methanol. In NHRA racing, there are two classes for fuel cars, Top Fuel and Funny Car.

I have no idea what declet is.
