Those of you who did V8 conversions...

Did you have to use Ramshorn manifolds on the 60???

Or do standard exhaust manifolds work??


I know you need them for a 40 but I am not positive that I need them for a 60..

I think both will work. I have the rams on mine, but we just did FJKai's and he is running 1 of each (ya, don't ask) with Mark's Adapter. There is so much room in the 60 for a V8 it's crazy.

Stock cast manifolds on the 6.2.

Cast rear dumps on my 82 FJ60

Right on...


Then the spagetti headers will fit with a 5.0

Also, how much did you offset the motor to one side (2" to the drivers side or...)

 

[Dynosoar]

Stock exhaust 5.7 TPI engine 1 inch offset to DS

I had to use ramhorns but I did it the red-neck poor college kid way and didn't move the tranny forward at all. I just beat the hell out of the firewall for a few hours and made the motor fit.

I wanted the shop that did my 5.7 Vortec to use ramshorns but they just had to use block-huggers. They dented one tube to clear the steering knuckle. I've had to replace gaskets twice. I'm just waiting to develop a crack so I can install ramshorns. They look like they could just bolt in.

I used block huggers b/c I was concerned that rear-dumps might put too much heat near the gas and brake lines near the firewall on the PS.

I used the stock rear dump chevy manifolds. I don't have the room for headers, we tried 4-5 sets but none of them would clear the steering gear.

Greg, interesting thought about the heat issue. I was told by the exhaust shop that all you needed was 1/2 between the fuel lines and the exhuast... sounds tight to me.

Surprized to hear about problems clearing the steering box. My #3 header tube clears the box by about 3/8". But each of these swapped-in trucks is a one-off, I guess.

 

[Gumby]

My stock rear dump on my 6.2 has been pretty well clearanced by cutting and welding the floor and firewall on the right side. A 6.2 is considerably wider than a 5.0 and it's set back to the stock location to clear the oil pan on the unlifted diff.

No room for much of an offset.

Every truck is a one off.

 

[Mace]

I think "one off" is the definition of bob

 

[Corbet]

I used a set of house brand Summit Racing block huggers. Ran the passenger side exhaust under the oil pan.

Offest the engine 1.25" to the drivers side if memory is correct.

mine are Headmans, fit perfect, I think they are made just for such a conversion, come out in about the perfect spot.
