MG MGB Technical - Engine for Sale

ENGINE FOR SALE - AVAILABLE LATE NOVEMBER 2003:

As a competitor in the MGCC Luffield Cars Speed Championship I've decided to move up to Group 3 next season and have asked Peter Burgess to build me a feisty 1950 Sprint engine which means my 1868 unit will be up for sale (no reasonable offer refused) in November. She's only done one season and is a year-old this month with about 4'500 miles (including 1000 running in miles) on her.

The full spec is as follows:

Built by Peter Burgess Automotive Performance Engineering.

Exchange engine over-bored to +60 thou to give a capacity of 1868cc and fitted with a fully modified fast road-unleaded cylinder head. Piper HR285 camshaft and new three-piece clutch fitted. Up-rated oil pump, by Wayne Martin @ Peter Burgess’s, fitted. K&N Filters with stub-stacks and richer carb needles fitted to standard Twin SU HIF4’s (Main jet size: SU 0.090 inches).

The full spec is:-

Block
Bore:81.78 mm
Stroke:88.9 mm
CC:1868
Compression Ratio:9.75:1
Rod Weights:851 gram
Piston Weights:456 gram
Crank Size
B/E Bearings:0.010
Main Bearings:0.010
Thrust Washers: Standard
Camshaft: Piper HR285
Tappet Settings

Exhaust:1.343” 21/4N

Exhaust:6037 x4

As you'd expect from Peter Burgess, she's an excellent engine a fits into this years (2003) Group 2A regs. She revs freely to 6500 rpm and the cam really kicks in at 5000rpm. She's been regularly serviced etc. and is genuinely in first class order. Depending on the rolling road used, she's either putting out between 110-115bhp or 115-120bhp.

She cost £2000 sterling new and I'll accept any reasonable offer. Delivery can be arranged within the UK, overseas purchasers would need to make their own arrangements.
