Is this a wood chassis car? 

If it is a wood chassis it is not suitable for too much in the way of power increase.

I am putting a 2 liter Alfa into mine, (probably not "modern" enough for you) but I am also using hot cams that will limit low end torque a bit.
I will also avoid drag-race type starts.

Richard, Marcos 1600

>In my opinion, the Rover alloy V8 is the best choice of V8s for the Marcos. As you mentioned, this is the engine that Marcos used starting in the mid-1980s. It is one of the lighter V8s out there at about 320 lbs and makes decent power, but is still relatively small displacement at 215 ci to 282 ci (3.5 liter to 4.6 liter). The engines are plentiful and cheap to purchase at U-Pull junkyards coming from mid 1990 Land Rover Discovery and Range Rovers. The bigger headache and expense comes in mating a suitable flywheel/bellhousin g/transmission. Probably the best match is the Leyland LT77 out of the Triumph TR8 and Morgan+8. I think there are also T5 transmissions that can be mated with custom bellhousings.
>I expect the heaviest engines used in the Marcos cars were the 3.0 V6 Ford and the 3.0 Volvo. My car came with a 2.0 V4 Ford that weighs at least 100lbs more than the Rover V8 I am replacing it with. I would consider the small block Fords and Chevys mentioned as too heavy unless you came across an all alloy version.

>>I bring up these questions because I wondered if anyone had a experience or thoughts on placing a Ford or Chevy V-8 into a 1600/1800GT (something like a 289/302 Ford or a 305/350 Chevy). Would these engines make the car too nose heavy and ruin the handling?
