Want to upgrade the very minor performance of my 1600tp and found CVD do Pobjoy machined blocks/kits which would perfect for me. My question is why would someone build up a 1776 over a 1916 for the same basic price? are there performance advantages betweeen them depending on application? A mate of mine had a 2180 in his back in the early 90s that went like stink(he didnt drive it very often though!) and I would like to build up something reliable but enjoyable!!

94's open up the heads more
"to some degree" you would be safer with 90.5's and stock heads

In the early days I believe 94's had a thinner wall and were susceptible to warping

things have progressed a long way from the 80's

A 1776 in stock or turbo form is still a popular choice.
There is also a gazillion 1916's out there and daily driven - mine included 👍

Nutshell - a mixture of personal and engineering choices

If youre going to do a full rebuild then increase the stroke as well and make it an over 2lt motor.......plenty of them as daily drivers as well 😉

Say I went for increasing the stroke, when does it become a stretch(so to speak!) to fit it in the engine bay without modifications. I have heard about the tinware needing extending, plug leads too maybe? Lets say I built up a 2180, would that require a lot of extra work to get it to fit?
Thanks for your patience

Also is there much clearancing needed in the block for a crank that size?
