has anyone replaced a rover v8 with a chevy small block & if so what problems/issues did you hit ?

I'm considering it as my next upgrade

The chevy small block is quite a bit heavier, especially if you are going to use the original iron heads. Been here before but the 4.8 of 5.3 lsx engines are very good value and are lighter and smaller than the old 5.7 chevys.
With the older chevy you would need uprated springs on the front, I assume it is going in the 90?

yes in the 90 was the plan, I was considering the chevy 5.7 as a cheaper alternative to the larger rover engines, but I guess I have to do the same spring upgrade as the gmc 6.2 v8 diesel

not quite that heavy, certainly cheep power though, with ally heads and inlet can save over 100lb on the weight.

Have a look round my site, I replaced my 3.9 with a 5.7 chevy - which still wasn't fast enough, so i nailed on some turbos for good measure.

I got an extra row fitted into the RR efi radiator and fitted an oil cooler.

You can reduce weight by using ally heads, ally inlet manifold, ally water pump, headers and mini high torque starter.

There was a pair of adapters on ebay the other day, just looking for it.

Here they are:

I love smallblock Chevys!

Still dreaming of making a boosted TT one at some point, preferably as cheap as possible

Guaranteed explosion!
