so ive been looking at a 351w roller motor. the casting is F4TE. what im wondering is if there would be any fitment problems for that motor in a 92 bronco with a efi302. will the oil pan for a 351 clear everything? will the efi upper clear the hood? the motor im looking at is a roller block for a foxbody mustang engine swap. will a motor bored .040 pass CA eissions? thanks.

 

also. what is a sportsman block and what makes it different from a standard W block.

--------------------
If the deck height is the same as a later 5.8L block (later deck heights are taller than the earlier pre 74 351w blocks) If they are the same deck height, then everything should bolt right on...

will the oil pan for a 351 clear everything?
---------------
So long as it is fit for a Bronco or 4x4 ford truck, you should be fine...The fox body swap engine has the dual sump oil pans and will need to be replaced with a rear sump oil pan...thus the oil pickup tube and pre screen will need to be mounted...I don't know if the fox body mustang engine has the main cap stud with the exposed threads for the pickup tube.

Having a roller motor has no effect on emissions testing nor does the bore size unless the bore thickness is too thin...also as long as the cam is conservative enough (if stock cam no worries) that the engine electronics don't get thrown off...

Having this in mind, make sure you have the same firing orders....same upper intake (lower intake needed) as the 5.8L meant to go into these trucks....

Do check into the CA (C.A.R.B.) emissions laws before conducting such a swap...If I recall correctly, you are only allowed to upgrade a 6cyl to a 5.0L
and not a 5.0 to a 5.8 for some silly reason...

Since the 5.0L look so similair, you should be able to get away with doing the uprade...it is hard to tell the difference.

So in a nutshell, get the 5.8 roller shortblock, and install the CARB approved heads on as well as the intake...pull the computer and harness off another 5.8L truck and call it a swap....just make sure ALL emissions equipment for that year (1992)truck are on it....

for example:air pump, air injection fitting behind the heads, all the valves(EGR, air bypass, PCV etc etc...), cat converter etc...

The installed intake heights should be extremely close if not similair with the most obvious difference being the intake width. Also pay attention to the exhaust collectors as they are wider for a 5.8.

keep in mind that the speed density system for a 302 may not work well with a 5.8 due to the different requirements of air and fuel...

do perform a search here and do everything possible to stay away from the referee....once they have you in the loop, you're screwed!!!

 

Well, a standard block is a production block with std tolerances and main cap webbing.

A sportsman block has thicker main cap webbings (and can be machined for 4 bolt mains), it also has thicker bulk heads for better high rpm rigidity.
the price is easily double that of a production block.

Ford lighting 5.8s had these blocks.

 

odd. i just found a 351 sportsman for less than a 351w.

what deck height would i be looking for (9.2 or 9.5")?

this is the shortblock im looking at:

http://cgi.ebay.com/ebaymotors/ws/eB...tem=2435614247

it doesnt say anything about oil pump location. there is no pan as it is a shortblock.

 

F4TE means 1994 truck, so you won't need to worry about the pre-74 deck height difference.

 

well i just found out the motor is a dual sump. now my question: are there any dual sump pans that will fit my '92 broncos engine bay?

 

you will not be able to use the dual sump setup, just get an oil pan off a 351 bronco or f150 and use that pan and pickup.

The block deck height should be a 9.5"

Although the current bidding may be cheaper....for now...it will go up...
keep in mind that current bidding prices on the bay don't reflect the current retail pricing at the ford racing dealers...

the oil pumps all mount in the same pace....but the pick up tubes are the ones that differ...our 5.8's carry a pickup tube that bolts onto the ceter main cap while running towards the rear of the engine...then the pickup tube drops off down into the rear sump and to the pick up screen shroud.

Make sure the block is not cracked and make sure the block is a low mileage unit as these blocks can only be bored to 4.030" oversize...safely.

Use all current smog equipment for the 92 5.8L truck or Bronco...

 

ANother thing is that that 351w block has the 4 bolt mains on it....

the sportsman block you saw is the 302 sportsman...

A normal production 351w block should not exceed $450 for block, caps, main bolts and oil filter bolt in mount

 

man id love to get an 'f4te' or within +/-2 yrs of that for $450! and no, look at the first link again its a 351 sportsman right under the 351w for 1195$, $700 less than the normal W block. also i thought it was the 351C's with the fourbolt mains, im pretty sure most all modern 351w production blocks are 2 bolt.

 

I am talking about the bare block, perhaps you are seing a shortblock?

 

hmmm i got mine for 1100....a sportsman 302 block runs about a 850-900...and this is for the nice thick main cap weebing and bulk head block...keep in mind that there is the sportsman blocks and the R SVO blocks with siamesed bores...

the block I got was a later production 5.8 block roller ready

 

OK...that is for a NORMAL non roller 5.8 shortblock....

it comes with cam, pistons, rings, bearings, timing kit/chain, melling oil pump already installed....just bolt heads, timing cover, pullies etc on and go...

all others are for BARE blocks...
