welcome mate
tbh id steer clear of the 2.8 as they are not the most tunable there are some people that will argue the fact that they are, if you have a very deep pocket to have the heads reworked to get shot of the power draining siamese port then you are well on your way, the essex lump is very easy to work with and parts and machining aint bank breaking if you want the six pot , if you want a good 4 pot then go pinto they are strong and easy to work as well, and remember the cossy was based on the pinto but to get a true 200bhp from a pinto your going to be looking at £2000 plus
