Hello All,
I’m new to the forum, but I think all V8 specialist are here...
I have got a Rover V8 3.9L engine with 4X2 Dellorto’s 45 on them out of a Replica.
That's all a knew, up till recently when I opened the engine for replace head gasket.( I found water fumes coming out of crank case ventilation.)
Hope it is the gasket not the block.
Engine looks new inside.
So what I know until now (thanks to David Hardcastle book+ this site) :
Engine is 37A…. so a 350I from TVR/Morgan.
The bore is 93.5mm NOT 94..mm so this indicates an early JE-Engineering upgrade to 3.9L?
Omega pistons
Crane high rev followers
Double springs (I would say also from JE-Engineering)
Cam? No idea. Probably also crane. I will measure lift height later
Valve train from EFI (acc. valves) with as far as I could see standard rockers.
Inlet ports are widened to the max.
Questions:
Which Headgasket to use? I already ordered a 3.9L standard 94mm composite. Is this usable for 93.5mm? A 3.5L gasket from” Fel-Pro Permatorque acc Hardcastle” is advised acc Hardcastle book?
What power range could someone expect from this powerplant?
What would I put as max rev limiter for this set-up?
Could roller rockers be a further improvement?
Thanks for advice. I need the engine ready for next meeting in Spa Francorchamps “6 hours”…..
PS: Thanks to te moderators for this great forum

Sounds like a nice set up! it seems to be a JE engine and could possibly be John's cam in as well.Why don't you give John or Richard a call they will answer all of your questions and sell you quality gaskets etc. Give them your engine number if John built it everything is on computer for traceability, just a thought Cheers Mark.

Hello Mark,
Aha..I've now reed the history of JE more in detail. So the founders were the builders of this engine probably. Yes I will give them a call. Thanks..
In the mean time I also measured the lift height and it was about 7.5mm at lifter +-. So 12mm at valve (1.6 ratio).
Also here a picture of the engine partially dismantled already. see link google fotos.

Marc,
It's a GTDevelopment.
I contacted John, but it seems not to be one of his engines.
He has always put a number on the block front near the deck on the passenger side row. I can only see a date.
But he gave me some advice and he's got a nice amount of performance parts on his Web-shop..
But I'm a bid confused there is also a firm JE Engineering now JE Motorworks the firm he has is JE developments. What's the link?
