276 cam
MG Metro Big valve head
LCB with RC 40 exhaust
Centre mains strap
Pre verto clutch assembly
Twin 1.5 SU carbs
Steel Vernier
10:1 ratio pistons
Straight cut gears
4 pin diff
Rally strengthened drive shafts
GAz lowered shocks
Stripped out shell with cage fitted
Front end removed but steel hinged front end fitted
Power steering (Vauxhall corsa modified)
Megajolt ignition/electrics
Twin tanks and electric fuel pump
Sitting on 10 inch minilites plus 7.5 S calipers and disc
Car should be finished in 2 weeks
What performance can i expect and handling its primarly a fast road car so comments appreciated

Use a good dizzy and high octane fuel. Possible to make an honest 90 horses. Many more horses might be ponies when truly measured. For sure your setup will be a pleasure to drive.
When ready, setup and tested, let us know your final outcome!
My mini was a stage 4 big valve 1275 with 286 Kent, double barrel Mikuni PHH44 and 1.5 roller rockers. Made also a 90-ish horses, suffering from a little too low compression, causing loss of flexibility and low rev torque. Currently this engine is re bored to 1380cc with forged omega's and Specialist Components Bimmer 16 RS K head conversion. Using 98 octane John Kimmens of SC told me the max static compression with these RS cams can be 13:1, so I made it a save 12,6:1

That pretty much describes my car! Apart from I've got a 286 and a 123 dizzy. Mine gets mid 90's so I would say low to mid 90's for that setup too.
Sounds like a nice car, should handle well if all the suspension is adjustable and setup correctly.
What diff ratio are you going for out of interest?

Interesting, just about the same as an engine I built almost 2 years ago but never got around to finishing - it sits in the corner of my office!
1310 based on a 1300GT with 11 stud head (Mk3 Cooper S). A+ rods with ARP bolts, Minispares 6cc dish Nural pistons, 276 cam carefully timed, lightened steel timing gear and IWIS chain, lightweight steel flywheel and pressure plate, all on a SC clubman gearset with a 3.44 diff. Will run on a single 1.75" SU with LCB and RC40.
I was expecting and honest 85bhp from this (the head has not been worked) but maybe I will be surprised!
Be interested to hear how it goes as I doubt I will get this engine in the Mini before mid 2018.

The megajolt set up has not been fully setup yet the car goes for a rolling road next week to do the finals to it, the garage got the engine started as through a laptop you can do that and hey ho she started, according to the garage it runs well but will be interesting to see the rolling road results
