Default Ford 300 motor

Changing direction on a inline 6 build. Was going to build a Chevy 292, but I am going to try my hand on a Ford 300 6.

Looking for a good/clean (no grease ball job) complete rebuildable motor in the Southern Calif. area. Also interested in hot rod performance parts for a 240/300 Ford Inline Six.

PM me if you have parts.

Good news, found a 300 inline 6, price was free, now that's a deal.

Will add a build thread to this site with pictures for those that may be interested.
This will be a hot street motor build that will run on prem. pump gas. I will lay out the complete build idea with parts in a few days. This build can be done on a 240 or 300 motor with 240 68cc heads or 300 76cc heads. Hope to make 250 - 275 HP.

Let's see it.

What's the 6 going into?

30+ years ago, there was a Vega prowling our streets... had a HOT straight 6 in it... it was quick and fast, at least for those days...

Dr Crankenstein--- Motor is going on a run stand for awhile. Later I may put it into a drag race altered T Roadster or modify a bit more 10.0 CR up to 11.75 and better P&P on the heads then into an altered.

Nice score, Tom. I sure hope you surround that engine with 4 wheels and a bit of a body and get it out to the strip.

Dr Crankenstein -- Thanks will post progress & pictures as I get going.

bobw -- Bob, I am like you and it is more about the build than driving these days. I would really like to see the motor in a short wheel base 95" bantum roadster at around 1850-2000 lbs. If it happens my old drag race partner will drive.


Just to get started this is some what the direction I am going, As always I am open to new idea's and helpful criticism

This is the basic motor layout.
300 block with standard cast crankshaft
Ford 352 Flat top pistons 4.030 w/3cc valve pocket after top milling .022 off the piston tops.
Pistons to block deck .020
CR 8.50 - 10.0
76cc head, P&P, 1.94 Int/1.60 Exh, 7/16 screw in rocker studs
BBC 1.7 roller rockers
Crower 19205 Hyd Cam & springs
HD EFI Exhaust Manifold
Dual Autolite 2100 1.08 two barrels
Home made plenum Intake for dual carbs

Hope to make 200 HP in this configuration on Prem Pump Gas

Stay toned for more

Picked up my core 300 motor yesterday, have not checked out numbers for the block or head yet. Motor has been disassembled and has original size standard pistons in it that have no marks on the piston skirts or the bore. This motor was removed from a farm truck when it had valve train problems. It is an EFI motor and the problem was it cleaned a bunch of teeth off the cam gear. As this was years ago the motor was pulled and went into the bone yard and new motor was installed. I would be surprised if it had a few thousand miles on it.

The head is a 300 that ran pedistal mount rockers. My question is how much has to be milled from the already flat bosses to drill and tap for screw in 7/16 rocker studs? Is the number .250? I will be running guide plates also.

Have posted over on Ford 6 site also.

Was able to spend some time going over the motor & parts today. The block casting number is F2TE-6015-BA so it is a 1992 Truck Engine. I reset the crank in the block and both the main & rod bearings are standard Ford factory units. I measured the #1 piston torqued in place to see how far down it was in the bore (.021") I was thinking it would be .040-.050". The pistons are original Ford standard units that like I said, no skirt marks & no cylinder wall marks. All bearings look like new. I really think this motor had only a few miles in a ranch truck and they needed it repaired ASAP so they pulled motor and put in a new replacement. This motor sat in their bone yard until I picked it up in 2010 for a buddy of mine. The rancher that gave me the motor is a race buddy of ours. 25% of the cam teeth were broken off.

Can not find head number, the chambers are heart shape with D dish pistons. Dish is .325" deep. Head used pedestal rockers and I want to convert to 7/16 screw in studs with 1.7 BBC roller rockers for this build.
