Thread: What engine

Look around for one that already has been converted (chev for example) and take it from there. i.e. swap bits. Hard to do a conversion these days.

The motor in mine is up to about 500,000 k's now and just goes and goes........

Yet that's why I thought about stroking the block I have as its a bolt in swap and all I would need to do is upgrade the norm to handle the extra power

Anything that keeps you away from engineering will be easier, as you know. And conversions just seem to keep on costing and taking time, from what I've seen. There's a funny comment somewhere out there about how you should double or triple your time and money estimates.

I'm been comtemplating the same thing for a Rover block. Which stroker kits have you been looking at?

The rangie has 254ks on the clock and the engine is starting to get tired in her old age so I've now trying to work out what engine to put in her

You know a well maintained ie oil changes every 5KK or so ,RV8 bottom end will be still in its youthful prime at that K. Mine has 210KK and runs 150Lbs compression more or less on all. That is with new cam and lifters and reasonably new heads.No smoke good oil pressure etc

Where they do get old and weak is that the heads need recoing to reseat the valves etc and clean the ports and the cam and lifters need replacing.It would also be an idea to fit new /reco modern injectors.

It will stiill not be a ball of fire , but much better than a neglected engine.

If it smokes or has poor oil pressure that is a different matter.You do not say whether it is a 3.5 carb/or 3.5 or 3.9 injection but the same applies to all varients really.
All that is needed (after an evaluation )is usually a top end freshen up.

Mine engine is a 3.5inj I'm only looking at building now so I can take my time

The kit I'm looking at is from RPI Engineering cost is around 3k then you have heads and machining ontop of that so I'm guessing about 6k all up depending if it change the injection setup to a injected carbi setup

listening to how much money you got , 350RRC ,is spot on , first off conversions if done even half well reliable will cost . the conversion will cost three times as much as buying an allready completely done job.
just how much HP'TORQUE you want ,or better still can afford ?I can get 250HP out of your 3.5 ,or 250HP out of CHEV/HOLDEN/FORD/ and 300HP for LS1.
Get real ,determine the budget first ,then look around for reality.
my present un-reality is the complete egine (LS2 6.0 LITRE) and the 6l80E 6 SPEED AUTOMATIC GEARBOX out of a VE SS . By the times its bought,freshened up,adaptered, custom exhausts/radiators etc ,the trans/converter redone ,compushifted $2000 alone)big time mods to LT230,etc etc. NO WAY , I could get get of this under a real $20,000 .

That's why I asked the question as in reality I have the 10.5:1 block so if I can do that up by stroking it then that would be my choice as its a bolt in swap but if stroking is far too expensive the I will just rebuild it with good heads and a good cam
As I have said before this is not a short term project I will take my time and do it properly

Just remember that those old blocks are weaker than the later ones , particularly in the valley.
They must have upgraded them for a reason and if you stroke one you are adding extra stress.!

Also don't those have a rope rear seal. Just a bit more machining I guess.
