    Retrotek Purchase

    Mines still on the shelf in my garage, I cant imagine if well tuned that it wouldnt beat a carb at least in throttle response and torque, are you using the ignition curve feature as well?

    Wtf is wrong with this combo?

    The heads are fine, TW heads flow about the same as an AFR 185 dont let the numbers fool you as the intake is closer to the chamber. I would agree with checking the advance curve and also fuel pressure.

    Opinions wanted on a 351w build...

    Jay is a bit.....Arrogant but he does know his stuff, years ago there was a guy named Denny Wykopff he did absolutely the best custom cams made, I went with Jay after not finding Denny anywhere. The comp xe274hr is still an excellent grind, you may call Joe Sherman Joe Sherman Racing he can...

    After market fuel injection??

    MPI is great BUT the new TBI self tuning systems like the fast ez efi and powerjection give multiport a run for the money, the new style TBI systems use high pressure injectors as well as wide band 02 sensors, the bummer with the ez-efi and powerjection 3 is there is no ignition control and the...

    Opinions wanted on a 351w build...

    I may be wrong but I think the only difference between the track heat and regular twisted wedge is the track heat is a non emmisions head and no exhaust crossover. Canfield is a great head but somewhere I heared they are out of business, Speaking of Jay Allen, you may want to spend a few bucks...

    Opinions wanted on a 351w build...

    especially with your cam and compression a super large head is overkill you wont see much if any gain untill 5-6k, the 185 is perfect but I favor twisted wedge heads the std 170cc works perfect on a 351w BUT the as cast 190cc TW head are the hot ticket, if you are going to dissassemble the block...

    Dont forget guide plates! if you buy aftermarket heads they will have guideplates and screw in studs already.

    Which cylinder heads is the best for 289 CID?

    with that cam and good heads 350hp should be no problem, I dont know how he is using that cam with stock heads/springs/rockers, I had 2 studs snap off in my 289 using a cam with .478 lift, usually around .480 lift is max with stock heads.

    Which cylinder heads is the best for 289 CID?

    flow numbers alone mean nothing, velocity, swirl, chamber shape, cross sectional area all come into play on cyl heads, look on AFR's own website under articles and look under MM&FF guide to 5.0 cyl heads, flow numbers and dyno tests with 5 different engine combos and just about every head made (...

    Which cylinder heads is the best for 289 CID?

    AFR 165's are a great head for a mild 289 BUT the twisted wedge 170cc head is much better, the TW head has 2.02/1.60 valves but has a 170cc int port, because of the design it actually has better flow in the low and mid lift than the AFR 165 and the AFR 185 and will not kill bottom end TQ in fact...

    My Real-World Test with Synthetic Oil

    I just put synthetic in my 1 ton duramax diesel pickup, I went from 15-40 to 5-40 synthetic, I did notice my oil pressure slightly dropped at idle, I will be making my usual 260 mile trip to the river tommorrow, we will see, usually at 80-85 mph I get about 17 mpg. I've ran synthetic in the...

    Ideas on 289 rebuild

    if you want torque then throw a stroker kit in your 289 block, like a 347 and a mild smooth idling cam and some aftermarket heads, you could easily add 80-100hp and a huge amount of TQ over the stock 289 and have a relatively mild stock sounding engine and on the outside it will look like your...

    Carb Help

    mighty demon 750 or mighty demon 750 annular, best carb I have ever used on my 408, worked better than my prosystems 950hp, almost perfect right out of the box. Call BG and give them your specs and they will recommend the right carb.

    about time for a new carburetor

    600 is not overkill at all but out of all the carbs I have tried even custom built ones the demons have the most performance and features for the money, a road demon 525 with annular boosters will give you efi like throttle response and will still flow about 600 cfm. Road Demon I have bought...

    351W Stroker vs 390

    like DH said if you have a 390 use that, you can stroke a stock 390 block to 445 and get some pretty good heads for it, a stock 351w block can go 428 but an aftermarket 351w block can go 460.

    Igntion advance on stroker

    yep, a stock 5.0 starter, I get a slight hot start problem but all you need is a start retard box, it retards the timing when cranking and then advances it once started. MSD Ignition 8982 - MSD Start/Retard Controls - Overview - SummitRacing.com
