I run an EN1 motor/ gbox in a Sporting Trials car.
These are off road hill climbers, the car version of Trials Motorbikes. This is not a speed sport, but how far can you go over natural obstacles on a defined course.
Spaceframe chassis, rear wheel, drive open diff, individual rear brakes.
The whole car weighs in at about 360kg The Honda Motor G/box is mounted north/ south Honda diff is locked and the drive goes into another rear axle.
result is very low gearing. I am after information to make the motor a little brighter.
The problem is we want low rpm torque, but with the ability to rev out high when we negotiate mud.
I run a Kelford cam that is tweaked for this, also lightened flywheel.
We generally run SU carbs to stop flooding when the car is on extreme angles. We constantly have bother with fouling plugs (crap petrol in Kiwiland )
Any information would be appreciated, keep it simple please like swapping stock parts

If you can get a 1751 from a 79-80 accord that should give you some torque and about a 53-5800RPM redline.(more if balanced!) If you get the late 80-81 block the flywheels are slightly different (larger) but the manifolds should swap from what you have.
Or if you wanted, just get a crank for a 79 accord and stroke your engine (you would have to offset grind your accord crank to make the EN1 rods fit thus giving you more stroke, but that might mean custom pistons because of compression/pin height of the wrist pin to get zero deck. OOOOOhhhh! I just get goosey bumps.
