FridgeFreezer Posted January 24, 2008 Share Posted January 24, 2008 Real Steel. A couple of bits I'd recommend are: Duplex timing chain Composite gaskets ARP studs rather than bolts Rubber rocker cover gaskets Quote Link to comment Share on other sites More sharing options...
Fatboy Posted January 24, 2008 Share Posted January 24, 2008 Real Steel via Clicky RPi are okay for bits (don't buy assemblies tho' via Clicky In addition to the bits that Fridge has recommended, get rocker post shims and take the time to make a little pair of gauges. Ians definitive thread in the Tech archive is an excellent reference. Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted January 24, 2008 Share Posted January 24, 2008 1st I would ask which Comp Ratio it is, being in a 90 means it could be 1 of many, if its a low Comp motor I wouldn't waste your money, and go get a 3.5 EFI one rebuild that and shove in for easy fitment of a load more BHP. If it is a decent compression motor then fine, ....why is it being rebuilt, ......and whats the state of the insides / Bore / inside rocker covers etc etc How much of a rebuild are we talking about here, ....and whats your budget. ? On top of this do you want (whichever the engine used in the end) to extract any more BHP ?. if so then now is the time to do it, but it will mean working it into the rebuild and workstream. For a std rebuild I would always suggest Block - chemically cleaned and a glaze bust minimum on the block Heads - skimmed to raise comp ratio to compensate for reduced comp since composite gaskets used, possible block decked as well Head bolts - Bin and use ARB Head studs Vandervelt Main and Big ends bearings, to suit crank - polish or a regrind ? Genuine Piston rings Mod to valley area 2x small holes at front of valley to assist oil drain back and timing chain lube Duplex Timing chain and steel gears RTV sump on rather than a gasket Composite head gaskets Use all genuine seals and gaskets inc late type rubber V8 Rocker doubries If heads are 2x spring per valve type - bin and fit a set of EFI heads Frankly on a low grade V8 / light (no insult intended) I would honesty say Shimming rocker posts is OTT and will gain virtually nothing For soft increase BHP of a carb V8 fit Piper 270 Cam and new followers Increase needle size in carb can't remember which ones but I have it written down if you need If you can afford - Block crank pistons flywhel assemble have balanced Bottom end build.... and then add EFI top end / heads and EFI system over the carbs (yes MS even better ) HTH Nige Quote Link to comment Share on other sites More sharing options...

Not really looking to up the power just doing as i had to . budget wise i was looking to spend around £1000 . Quote Link to comment Share on other sites More sharing options...

Not really looking to up the power just doing as i had to . budget wise i was looking to spend around £1000 . 9.35:1 is a goodie Whats the timing cover off, and also the heads - please advise ? Frankly you can buy a set of EFI heads and wiring bits bobs etc and gain BHP and smoothness,..... In fact someone was selling an complete efi unit set for £100, look in classifieds ? With a (sensible) budget of £1000 theres quite a lot you can do on the list above I posted Nige Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted January 24, 2008 Share Posted January 24, 2008 For that kind of budget I'd consider putting a chunk of it towards sourcing an EFi setup and Megasquirt'n'EDIS, that will give you greatly improved power, and driveability, plus better economy and of course water resistance. You don't need EFI heads to run EFI, the notch for the injector spray is miniscule and I doubt it really makes a great difference. If you're bothered, get the dremel out while you're rebuilding it and make some notches. Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted January 24, 2008 Share Posted January 24, 2008 What is Megasquirt'n'EDIS ?? Paul Nige's MS'n'EDIS install - everything you ever wanted to know and more Look at the Rover factory figures: 3.5 V8 Carbed = 130bhp 3.5 B8 EFi = 160bhp And that's with the horrible horrible flapper setup.

Bull Bar Cowboy Posted January 24, 2008 Share Posted January 24, 2008 I can easily get a 3.5 to 180 bhp without a lot of effort…………..

Hybrid_From_Hell Posted January 24, 2008 Share Posted January 24, 2008 ^^^^^^^^ Wot they both said heads wise what you have (pre 1988 EFI heads) there is little difference between them, later heads after the twin spring ones ie what you have are OK for unleaded and the main differences between these and "Efi" heads are waisted valve stems slight port changes and a tweak for where the injector goes. If your heads are in good nick and you DON'T go EFI or Megasquirt (which for £1000 rebuild would be very easy indeed and mainly nuts and bolts - and theres a load of help here should you need it) christ where was I , oh yeah then stick with the heads you have if you keep carbs ....which I think on a £1000 budget rebuild would be a huge smahe and a missed opportuunity If you went EFI as a 1st step to MS this would be hugely cheap, you could go either Flapper EFI (up to around late 80s) or even go for 3.9 Hotwire system (your 3.9 and 9.35:1 and skimmed heads / block wouldn't be too overfuelled IMHO, and hotwire to Megasquirt is the way to go IMHO vs Flapper to Megasquirt (although some "Northerners" do it different eh Rog but then again the atmospheres totally different up there ) oh and 3.9 heads ARE better than either what you have or later ones ...buy a 3.9 turnkey maybe and rebuild this in peace and quiet over time then rip out your 3.5 and replace the entire unit easy peasy Personally if you have £1000 to spend on a V8 Rebuild shoving SUs back on would be a shame Nige Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted January 24, 2008 Share Posted January 24, 2008 I have to disagree with Nige slightly, the only real thing to choose between flapper & hotwire is the later injectors are clamp-type not hose-tail, and they don't need a resistor pack. The flapper setup is simpler and less fussy, electrics wise, but I wouldn't keep either setup with your budget, I'd go straight to MS.

All me point was (oh MS Guru Fridge sir) was flapper injectors + pack etc is not as "Nice" to Megasquirt (unless of course your a Northerner ) at a later date as a Hotwire injectors rail etc - and no resistor pack etc IF you were to do Lucas EFI 1st stage and then to Full Megasquirt - but as with you I would say grab a hotwire system and Megasquirt it as part of the rebuild, 3.5 you have now plus 3.9 heads and nice cam and a MS would be loverley Nige Quote Link to comment Share on other sites More sharing options...
wkw90 Posted January 24, 2008 Author Share Posted January 24, 2008 Well i think i ll try to get hold of a 3.9 complete with all its bits and start from there , how is it i have gone from a simple rebuild to this Quote Link to comment Share on other sites More sharing options...
