The above post is very helpful.
Probably about 85 at the fly, depends on the head work.

Its a good cam but its going to give you a lumpy idle. Depends what type of driving you are going to be doing in the car?

First of all 'd change the exhaust, as an lcb with 2" pipe and single box gonna improve only loudness. Go for a 1,75" exhaust from maniflow or a RC40 and about silencers, keep in mind that a single box system its very loud.
What clutch and flywheel you goin for? That setup sounds to me good for mid to high revs, dont expect power under 3k rpm.

I'd loose those rockers. All they'll do is raise where the power comes in to an impractical point for driving in traffic and the like.
Put the money towards an ultralight flywheel and an RC40 exhaust...

Loose the rockers and get an ultralite flywheel.
The Kent286 is a really nice cam. Tickovers a little lumpy but it pulls really well. I had the 286 in my 1293 and that went like a rocket.
Depending on the head work you should see 85bhp+
I had 85bhp at the wheels of mine, and that was a 1293, but the head was worked well and the ports were fully opened.
You dont need to get 1.5 rockers, look for pressed steel rockers, they are cheaper and they are more than capable of handling upto 120bhp
Also look into getting a 4pin diff, as the Diff is the weakest part of the gearbox.
