wich gearbox

[henk]

hallo

i had my first go on the 400 meter in chimay i only road once because i drove my car over there and had to get back home
i did a 16.70.the engine is a 1776 with stock heads and valves so i am happy whit that for my first time but offcourse i want to go faster
so next time i gonna put some lower tyres on it.
i am also running the stock '67 gearbox so slightly longer geared but should it make a big diffrence if i use a shorter geared gearbox like on a '65or'66?

Is your 67 gearbox originally from a 1500cc car?  If it is, it has a 4.12 R&P.  Going to a 4.37 R&P from a 1200/1300 car will get you down the track faster.
Another way to go faster is to upgrade the heads/cam so your rpm range is increased.  Then make the run in 3 gears only.

Faster is a combo between engine and gearbox and driver
Swapping for a 4.37 gearbox is an option and less costly then upgrading the engine.

I would do both for more 1/4 fun

the gearbox is the originele one from the 1300 engine

Then you have the4.37 r&p gearbox i bet.
Put some money in the heads,decent header and carbs and cam

hallo

carbs and cam should be ok all ready i think.
they are 44IDF and engle 120
i also have 1.25 rockers laying arond to put in place

[Bruce]

You need bigger heads to run those carbs and cam.
