I was reading today about the 87efi model having 10hp less than the 88efi model. I did a search and it says the 87 has 8.8:1 comp vs. 9.3:1 in the 88. I know there are other differences between the two models but can you just swap out the 87 pistons for the 88 pistons? I can get a set practically for free so I want to know it I should even bother. Also do the pistons have a 19mm wrist pin? I've been trying to think of other cars with 83mm bores that might work (doubtful) the only one I can think of is the 5m/7mge.
