    Correct Push Rod Length & Lifter Pre-load?

    I just rebuilt my 1965, 289 and installed 1993 Cobra GT40 heads w/ Scorpion pedestal 1.6 roller rockers. I’m running a new Hydraulic Flat Tappet Camshaft (see cam card attached). My stock 289 pushrods are too short. So I bought an adjustable push rod to get the correct size... My question...

    Engine 289s W/ Gt40 Heads. What Pushrod Length Did You Use.

    Attached are a few pics of my GT40 heads off a 93 302 cobra installed on my 289 w/ Scorpion roller rockers. My stock rods are too short. I just got an adjustable push rod and I'm gonna mess with it till I get a good wear pattern on the valve tips. Any suggestions on what length I should start...

    Upper Control Arm Was Shimmed?

    Ok Im better read. Here comes the questions. I plan to use stock replacement parts, so non-adjustable factory stuff that will require shims. I understand how the shims adjust caster and camber. Also with the caster/camber guage in the link above setting camber will be a breeze but setting the...

    Upper Control Arm Was Shimmed?

    I figured I would do my upper and lower control arms while I have my engine out and I discovered the drivers side was shimmed out about 1/2". All the shims fell out and I removed the UCA and I have no idea how many were on which side. I'm assuming the shock towers have gotten weak over time...

    Main Bearing Clearance At .0015 For 289?

    I will run 10w30. Should I run an additives? I don't want too. I used assembly lube on all parts needed and gooped the cam / lifters up real good. I'm just waiting on some valve train parts to I can set up my rockers and hope to get it installed in a few weeks!!!

    Main Bearing Clearance At .0015 For 289?

    I had my machine shop undersize my crank by -0.010" and I bought +0.010" oversize bearings. I ran a strip of green Plastiguage and got .0015 clearance on the mains. Is this OK? I was shooting for .002-.003"? Thanks in advance!

    Newbi Gt40 Rocker Head Question

    I think I will buy the Ford Racing from CJ's. I was originally going to buy a 1.6 vs. the 1.7. Is the 1.7 ratio going to be an issue w/ my setup? My 289 was bored to 4.040 and I am using slightly milled Ford Cobra GT40s heads w/ 63CC chambers (we guessed 63CC due to the milling). My...

    Newbi Gt40 Rocker Head Question

    I bought some rebuilt gt40heads for my 289 (non p), cheaper than rebuilding my 289 heads. I know about the combustion chamber size will affect compression and am correcting this with new pistons. Castings are f3ze aa & f1ze aa I was told these are off an actual 5.0 cobra. I bought these bare...

    289 Re-build W/ Gt40 Heads - Need Suggestions

    Good feedback!!! The place I'm buying the master engine kit from wants to sell me what they call their 272 cam. (272/272 lift .475/.475). I think after your comments I'm leaning this way. I meant $100 for Speedways ford Sportsman Rockers & studs. Thanks!!!

    289 Re-build W/ Gt40 Heads - Need Suggestions

    My machine shop suggested I install flat top pistons to make up the compression. My current pistons have a 1/8" deep half dollar size dish to then w/ valve reliefs. Makes sense to me. I was considering a camshaft with 204/214 degrees & .448/.472 lift / exh. Is this too little of a cam?

    289 Re-build W/ Gt40 Heads - Need Suggestions

    The 3:50 gear and heads have to stay, no changing these items. I'm ok w/ 250HP+. My buddy has a stock 95 5.0 Cobra and I think its power is comparable to what I want.

    289 Re-build W/ Gt40 Heads - Need Suggestions

    Finally got around to rebuilding the engine. Would like the engine to put out 275-300HP on 87 octane pump gas w/ milage in the low 20's......if possible. More concerned w/ OK-good milage for long trips and stop light to stop light performance. I'm looking to build a daily driver / street car...

    Tips On Buying Used Heads

    My machine shop is going to charge $6-700 to rebuild my stock 289 heads. I considered buying cheap aluminum Flo-Tek heads from Speedway Motors for $369 each + $100 head bolts + rockers $200 = $1,038.00. Please I don’t want to do the china quality debate, as this is all I find when searching...

    Stuck Harmonic Balancer Bolt - 289

    Never mind, I was just impatient. It soaked long enough in WD-40 while I typed this thread. I hit it with the impact and it cam right off this time!
