I had a 4.6 engine with Merlin heads that I ran with wasted spark ignition. CR around 10.5:1 and healthy hydraulic cam. Total advance ignition was 30 degrees, that is what the engine was happy with. On rollers the power peaked at about 5600-5700 rpm and then started decreasing. Just for fun, we put ...

Also the rocker shafts may be of bad quality. I still have a pair of unused aftermarket shafts that were smaller diameter that the worn part of factory shaft. Oversize rocker and undersize shaft = almost perfect :lol: Ball bearings are impossible, needle bearings could be possible but apart from str...

Here is the final package. The spacer for propshaft is a 1,25" thick piece of aluminum.

I got lazy with the gearbox crossmember. I used to tease my late father about him getting old when he no longer fabricated everything himself and bought something ready to fit instead. Seems that I have reach the same age. I bought a Volvo 760 + ZF box set of gearbx mounts and crossmember from Swede...

Here is another photo showing the boxes from above. ZF is way bulkier even if the length is just about the same. I bought a new 3500 SD1 propshaft from Rimmers. Even with the spacer replacing the BMW rubber donut the current propshaft was too short. The new propshaft needs to be shortened roughly 1,...

An update. Crossmember finalized and gearbox is now more or less in final position. There is enough room in the tunnel after bit of a hammertime. Here is a photo showing the LT77 and BMW box next to each other.

My R380 is different in the front cover area too. Maybe because it is a commercial box, maybe not. Here is a photo of the R380 front cover plate. Two things: yellow arrow marks the release bearing arm pivot point. It´s roughly 1/2" taller than LT77. Red arrow shows the general shape of the cover pla...

Finally some progress with the gearbox swap. Old engine and box was removed as a complete package. BMW box was fitted to a spare block and trial fitted to the car. The space was almost perfect. I shaped the tunnel around the LT77 when I did the conversion over 20 years ago and deliberately left some...

Does anyone know for certain which axle type SD1´s have, Salisbury or Dana ?

Would be interesting to know.

TVR 5.0 engines have valve pockets machined in the pistons. Whether or not this is required, don´t really know. Another thing to check: these heads have bigger valves and in a smaller bore of 3.5 litre engine they may be close to cylinder wall.

Are you planning to keep the intermediate cover and serpentive water pump ? I think that you can run the pump in opposite direction since the vanes are in certain angle to the rotation. It will physically run backwards but not pump that effective. Maybe someone has tried this, though ?

Why not Haltech ? it´s local to you (well from Europe´s point of view anyway )and there should be plenty of tuners who know Haltech software.

New style front cover should block the path from the old style pickup. You can fabricate a flange to cover the old pickup hole in the middle of the block. Sometimes the priming takes a long time.

Do you crank with the spark plugs innthe heads ? If yes, remove them. You will get faster spinning crank and it way help.

Oil cooler fitted ? Cooler hoses fitted the wrong way ?
