    molded plastic wall thickness is very thin. would be careful trying to enlarge ports. or maybe chfrb says it is ok since they deal with modding the NS alot.

    There IS a bit of cleaning up to be done, but not much. be careful with that Dremel burr.................too much and the bolt bosses crack.

    This is a 2000+ manifold, but the idea is about the same..................

    man, the aftermarket FI stuff is pricey. a mpi system is 2000 easy. the northstar 4 barrel intakes are 500 but are pretty nice. add 500 for a nice carb and your at a grand now.

    I guess when you are spending the Grand Kids inheritance for good car parts, that it is a good thing. Yes very pricey, but @450 HP with 288 cubic inches with pump gas is OK for me. It is the same today as it was yesterday IT COST MONEY TO GO FAST, HOW FAST DO YOU WANT TO GO. With the whole engine deal, Heads, Cams,Intake,Computer, Wire Harness, Ford Injectors,Throttle Body, new fuel pressure regulator,fuel rails and assorted plumbing, new in tank fuel pump, it starts to be very pricey for my limited funds. I have planned this for 10 years and now is the time to GETERRRRR DONE. LIFE IS SHORT, DRIVE A HOT ROD

    Re: My NorthStar Head Stud installation picture

    Exactly ^^^^ - the 455 Olds engines I build for boats come in at around $7,500, running. And that's a basic, bulletproof workhorse. Get into roller cams/lifters, complete electronic ignitions and throttlebody FI and you're close to $10,000.

    I still wish that at least some of the Northstar engine upgrades could be stuffed into a FWD sidewinder package but it ain't gonna happen.

    So sad, it would take a Electrical Engineer, Computer Engineer and a Mechanical Engineer to do a deal like that, but it could be done, but way pricey out of my league.

    Re: My NorthStar Head Stud installation picture

    Jim I have that 455 out of my Olds now. The body was crushed. I'm looking for a better style car to fit that into, maybe an old mid early-late 70's Cutlass. If I want to spice that engine up a bit, should I send it over to you? Funds will be limited for some time- maybe two years down the road I'll have some cash to sink into an old iron block, RWD project. I'd love to have you build it up. It runs great just needs a bit more power.... I can seriously imagine a '97 Eldorado with a RWD setup and an old iron big cube V8..... I love the Northstar but that would just be downright cool- and time consuming to build!

    As far as I know within the next 30 days I'll be visiting some prospective U.S. States to set up a U.S. shop. I may have to take time to visit a few people. Florida is one of them, Texas is another, and a few more I'm considering. I'll be looking at climate, geographic location, population centers within reasonable driving distances, etc...

    Speedygman, I just may stop by to say hi and see your beautiful project first hand.

    Re: My NorthStar Head Stud installation picture

    Jake, I'd be glad to do a 455 build for you, BUT - consider this: truck freight and crating. That's a 750# engine.

    A 455, as you know, is a piece of cake to overhaul/build, and the aftermarket parts availability is fantastic - you can find multiple variations of any engine part. Surf through Performance Automotive Warehouse (PAW), Mondello, and Dick Miller Racing (DMR) catalogs for starters. (A set of Mondello street ported heads is now over $1500). I have not used Edelbrock aluminum heads to date due to concerns about heavy marine manifolds and exhaust piping. Get Joe Mondello's Olds "Performance Products - Technically Prepared" paperback catalog - every engine spec and all torque settings as well as slews of build and gasket seal tricks.

    A good block and head cleaning. ARP bolts all around. Valves, guides, springs, locks, retainers. Keith Black 10:1 pistons with Sealed Power moly rings in whatever size mikes out. Clevite mains and rod bearings. Complete FelPro gasket set. A Cloyes double roller timing set, advanced 4 degrees (don't forget the oil slinger ring). An Edelbrock Perfomer intake (not the RPM version) with Mr.Gasket intake gaskets, Edelbrock Gasgacinch for sealer - that setup gets you away from the valley tray "bathtub" intake gasket. A clean QJ with electric choke. March makes a serpentine belt kit. There's a cam cover in the valley. I remove it and drill/chamfer a drip hole above each cam lobe for additional flat tappet lubrication - not necessary if you go to rollers. Stock performance lifters. Mr. Gasket (expensive) valve cover gaskets #5875 and exhaust manifold #5945. I degree all my cams, but if you use a Comp mild grind or one of the Mondello (Engle) street grinds it's not necessary - they're dead accurate out of the box. Use the stock distributor with a Pertronix module and ACCEL 8mm wires, NGK Iridium plugs.

    I could rattle on and on, but if you run into problems, call me. Same number as before.
