Series Heads

[Dave (Kent)]

Hi all.
Does anyone know if a Series 3 head will (successfully!) go on an early "a bottom end?
Thanks

How "early" is the bottom end you intend to fit the cylinder head to?

[seaton]

assuming we are talking 2.25 petrols ther are two blocks one is a three main bearing job, the other is a five. There are 3 different cylinder heads
ERC5900 is 7:1 c/r wich is for 3 brg engines and suffix A, 5 BRG units
ERC5266 is as above but 8:1 c/r
ERC9099 is for engine no.s 36123672b, 36407286b

All the above info is from the series 3 parts book.

It's intended for an early ('63) 2A with 3 - brg crank (2.25 petrol). At the moment I'm trying to decide whether to make the most of what Rover gave us(!) or say 'sod it' and go the V8/V6 route.

I'm considering Turner head and maybe ACR exhaust.

I went for the V8 route, conversion was quite simple, insurane was cheep and the performance was excelent.

I've driven a 2.8 ford V6 powerd Series II, and if i'm honest it made a better road engine than the V8, but wasn't as good off road. Also insuane would have been a nighmare for me, as long as i used Rover parts the insurance compamy wasn't to bothered.

Tuning a 2.25 can give similar performance to a carb feed 3.5. (but with out the v8 rummble whats the point? )
