Project 36/400 T350R
Discussion
Small update. Bottom end is built up. Head has had some light porting work. Reprofiled cams are next on the list then the head can go on. Then making up the new exhaust system and fitting the modified throttle bodies. Then into the car. Still a bit to do yet but it's getting there bit by bit.

Very interested in this particularly if it ends up being a productHi RS .. there's nothing special about the build at all .. the bottom end and chains is all std with parts from tvr power incl head gasket. The head studs are from racing green. cams are bespoke. rings are total seal gapless top ring set. airbox is from clivef to my short lengths (made in stainless because I need to be able to weld to it for another project of mine). exhausts will be modified with less severe bends in, but i've got a different gearbox mount which allows me more freedom under the gearbox than std cars. head is tidied up in the valve guide/throat area but the rest of the ports are left std, they flow more than the valves already so no point doing anything in the straight bits. so nothing out of the ordinary at all.

Tvr Power parts may not be special but the parts I sell are the same as the 200,000 mile engine of Mr Shorts t350 , I challenge any company to better this achievement Dom

I have no beef with TVR power parts, but that conclusion appears to be made on a sample set of 1! If Mr Shorts engine had have gone pop at 10,000 miles I'm sure you wouldn't be saying all your parts are sDom

Hi John .. the little 3.6 has been the most reliable engine we've ever had, no other sp6 engine has lasted a whole season .. so it's a case of better the devil you know 
Plus plenty of other people are pushing bigger capacities and exotic cam control strategies, albeit at a price. I'm interested in seeing what the 3.6 can do as much as a technical excercise as anything. There's little point in me competing directly against the likes of tvr power and racing green, I just can't afford the time and money those guys pour into their r and d. So there's many reasons for sticking with the 3.6, it's been a cracking little engine for us so far. touch wood
Tvr Power is soley run out of my own pocket as for time i'll put 24/7 into my business, as for R&D its my time & knowledge so its not actually down to money, my old saying is "He Who Dares Wins" for the records im not from a rich family never had money handed down and im proud to say i was bought up in a very run down part Coventry (Bell Green) in a council house!

How many TVRs have achieved 200,000 miles? let alone ones rebuilt by TVR Power!!t, they only last 10K.TVR Power have achieved this with a rebuilt speed six, How many other builders have??
Credit where credit is due, there are quite a few TVR owners on the forums who have had there wallet raped with promises made by engine builders that have failed to deliver, it seems to me that TVR Power have delivered well built engines and not just the odd one, many many Rover, AJP and SP6 engines are out there achieving trouble free miles, not many have done 200K miles but plenty are doing good miles.
Just a (almost) final update on this project. Well 36/400 is a little optimistic right now, but only a little. It's project 36/395 at the moment but the exhaust silencers I've got on there right now are 2.25 inch which means I've had to sleeve the intermediate pipes down from 2.5 inch .. I think with a decent exhaust on it would be 400hp. At the moment though I'm quite happy with 110bhp/litre.
Here's the graphs. The rpm scale is slightly out, the rpm limiter is at 7800rpm rather than 7400 ish that shows on the graph, so the torque is exagerrated, it should be more like 308lb.ft rather than 320.
updated with a better graph
