    That hole is for the exhaust srossover that runs under a stock intake for manifold heating/egr valve, if you're using an aftermarket intake they will be blocked off

    Might be worthwhile looking up bill hooton on Facebook, he does barra looms & ecu's to suit sohc, he may be able to make one work on a crossflow

    Looking for Hydraulic lifter recommendations

    It is a pain in the arse, but pulling the original lash adjusters apart, cleaning them and re assembly yields a better result 90% of the time, the aftermarket lash adjusters just don't seem to last very long before they become noisy

    The V8 t5 isn't any better than a 6 cyl t5 as far as strength is concerned, I don't know why they are longer, there could be a bunch of reasons for it

    I don't know, I've never come across a V8 flywheel to check

    There's alot to go through here and I'm guaranteed to miss something but the short answer is using a 6 cylinder t5 and a crs or modified 4 speed bellhousing will put the shifter through the stock hole in the floor, a factory xf t5 (or modified single rail) crossmember will work and a stock single rail (assuming stock diff) tailshaft will work, off the shelf headers will work too (factory eb-au ones are garbage and will interfere with a right hand starter Windsors and Cleveland's have the same engine mounts and bellhousing pattern and their relationship to each other is the same for both engines, a Cleveland has a taller deck height and physically larger heads making a Cleveland taller and wider than a 302 Windsor bust slightly narrower than a 351 windsor ( 302 Windsor 8.2 inch deck height, Cleveland deck height 9.2 inches, 351 Windsor 9.5 inch deck height The path of least resistance for what you want to do would be to use a 6 cyl t5 (preferably e series falcon) and a crs or modified stock bellhousing (you will have to get a flywheel to suit, make sure it is one that has a 50oz balance to suit the roller windsor, a stock or upgraded e series t5 clutch will work) with one of their trans mounts (or make your own) the rest of the stock driveline should work

    Will 250 2v fit on 221 Block

    It should bolt on, I can't remember if there's any oiling differences in the early pre xflow's compared to the xt and later engines, but comparing head gaskets should be able to tell you pretty fast, there is one downside if it does all work, you will find a decent drop in compression

    It does, but dads a has a bigger fuel system than what is supplied with the sniper kit

    Its semi return less, the reg is right near the tank and fuel pump and returns without going to the engine first

    The number is usually in either of these two locations

    I love the holley sniper we put on dads clevo, the only downside I've seen is they can be rather finniky with dual plane intakes Before After

    You will need to look on the opposite side of the engine, Australian 5.0 had a left hand starter the yank ones didn't, if you look on the opposite side where the starter would be with a right hand starter you should find your engine number

    A few things to consider, converting an efi 5.0 to carb is exceptionally easy, its everything else that will give you headaches, any carb intake and non ecu controlled distributor is all you need and the engine will run like it was born that way. Here's the list of obstacles you will have to overcome depending on how much of the 5.0 stuff you want to use Fuel pump/ timing cover front accessories: If you want to run a mechanical fuel pump you will have to change to an earlier timing cover with a fuel pump boss and you will have to fit a fuel pump eccentric to the cam, this will also mean you have to change to an earlier waterpump as the 5.0 ones spin the opposite direction, alternator, p/s and a/c (depending on what your using) will all have to be v belt style and brackets as the serpentine set up won't work with an early timing cover, you may have to source a different balancer depending on what pulleys you need, it is very important to a 58ounce balancer and flywheel with a roller 5.0 a balancer to suit an early 302/289/260/221 will cause massive vibrations and possibly break the crank, if you want to use the serpentine setup you will have to use an electric fuel pump The trans you have if its from a falcon is an Australian only btr 4 speed auto and is a very different unit from the aod and aode's the us 5.0l used, these btr's are an electronic controlled auto and very difficult to set-up to run as a normal auto without using the engine ecu to talk to the trans tcu, I know shiftkits Australia make a standalone controller to suit btr's but as far as I'm aware they only have a manual shift option they can't be put into drive and shift themselves any more, c4 or c10 can be used behind the 5.0 and if you use a Cleveland c10 the holes in the flex plate are in the correct location for a Cleveland torque converter, if you use a Windsor converter you will need an aftermarket 58ounce flex plate to couple everything up (another thing to consider is the btr has a left hand starter and off the shelf headers don't clear it) As far as the factory heads go gt40p's are the best iron head but the relocated spark plug means most off the shelf headers don't fit and stock cast iron manifolds don't fit these heads either, you don't want to use the stock 5.0 headers as they are garbage and flow worse than the cast iron manifolds early windsors had
