If i wanted to rebuild my 186 to its most powerful potential.. What would be the parts that i would replace.. For example.. Rockers, valves, crank, flywheel, camshaft, Head and so on.. And roughly what would the price for all parts..? Around $4000 for parts maybe?

Full potential as a 186 - replace everything but the crank. Full potential as a Holden 6, replace the crank ie make a 202 or 23x stroker. If you want to stroke to 202 it's cheaper and easier to use a 202 block.
Cost of parts - not that sure, maybe more than $4k if you use a new alloy head.

Gooley,
you would have to put around 3,000 into iron head alone cam 400 for solid flat tappet with lifters,flywheel y/t l/weight 430, plus a few thousand for block machining and pistons and stuff then add induction and ign stuff if you did not have them already.
Thanks Hayden

How long is a piece of string?
When I was involved a little with Touring Cars in the early 80s, I think from memory the V8 motors were about 15 grand a pop. And due to the rules, they werent near their full potential. But at the same time you could find a "fully worked" 308 in the Trading Post for 2 grand.
I know you are talking 186 but I think the principal is the same

If I were to go back thru my receipts my 234 cost me $10000 and it doesn't run yet...but I am sure i could do it again for $6000 ish
YT head $150-300
Headwork $400
Stroker kit (cullen or prostroke) $1500
machine work $1000 ish
Turbo kit $3500
Sump $300
Cam $200
sundries (lifters, cam gears, pushrods, gaskets..the rest of the stuff to get it going) $1000-1500

to get an i dea of the costs it is virtually the same as a 202 in Group N to build a 186.
But even in non stroked ie 186 +0.060 against 202 + 0.060 bore there is still significant HP differential
The Top HP 202 in Melbourne are getting 320-325 HP My 186 is probably 270 at best
main difference there is Im using a flat tappet cam and all the good 202's are using roller cams.
Ask greg (82911) there is at least $3,000 between a f/t cammed engine and a roller cam engine in set up costs alone, plus ongoing replacement parts
Lifter bores , roller lifters, differetn pushrods,
different V/Springs and caps and colletts
just dont bother to go there( Roller cams etc)
240-260 is reliable but not on pump fuel
cheers
