CVPI drivetrain

[Hotraudmerc]

Hopefully there are some informed CVPI people here.

I have a line on getting a rolled 97 CVPI with 47k miles on it. I am considering putting this into a 49 Ford F1 truck. My goal for the truck is a street machine that is reliable and consistant enough for my older son to run amature bracket races with it. I understand these motors run forever if cared for. Anyone know apx what the HP and Torgue ratings are for this year CVPI and are they worth dealing with. The swap will be a lot more involved than doing a 302/351 but I have grown to really like the Mod motors since owning my MM. I just do not want to get started on something I will regret later.

Any thoughts.

IIRC a 97 is 205 or 210 HP

[Hotraudmerc]

I thought the CVPIs were 250 hp? Guess not.

How are the 2V motors for modding up more power.

The '97's did not have the PI (power improvement) heads. You can swap those on, it's a big mod for the SOHC Mustang crowd. I forget when the PI's were put on the CVPIs, but I think that's when they jumped to 220-225hp.

The SOHC motors seem to take power adders well, I've personally seen a number of centrifugal supercharged 4.6 SOHC Mustangs that were putting out some serious numbers.

You are right, an old school carb'ed 351 or 302 would be an easier swap.

The SOHC is a good motor, and if the money is right on the deal it could be worth it. But you'll have to figure out how to adapt the modern electronics to the new car. For instance, electronically control engine management, transmission management, and some other functions may be built into those boxes like the ABS and even traction control if the CVPI's of that era had it.

I'm sure others have much more knowledge on these systems than me, but just keep in mind making these standalone without the rest of the car could get tricky...

A simple standalone carbed motor and C4 or C6 trans would be a heck of a lot easier most likely...

[Hotraudmerc]

Yea I plan to use the entire cars electronics minus the guages and streering column. I am not sure how the engine management interfaces with ABS etc.

My Jeep uses the rear ABS tone rings for speedo which made it a PITA to put in the Currie High Pinion 9 inch I had made for it. I ended up swaping in a Slip Yoke Eliminator on the Tcase than used a Lokar speedo pulse senor rate converter and tapped into the speedo input down stream of ABS. I do not have ABS now but did not care for it on my Jeep anyway.

I am familiar with doing some of these tweaks but really do not want to create a huge headache.

i had a 97 and they were rated at 210 horse . really boggy down low...... 98 was the first year for the p i heads as well as alot
of other changes . i forget how much torque 97 had as well as h p inmprovement with p i heads.................

i think the current ones are

[RF Overlord]

1997 had 190HP / 265TQ (single exhaust) and 210HP / 275TQ (dual exhaust).

You can get a number of mods for the SOHC motor...underdrive pulleys, bigger throttle bodies, headers (from Dennis), throttle body spacers, PI heads and intake, PI cams, blowers [from Dennis (Vortech) and ADTR (roots)], custom tunes...

Due to the PCM being EEC-V, The catalytic converters with the monitors wil need to be used. Also, the fuel system on the 97 CVPI is the same as our MMs. It would require the use of all of the evap equipment or the check engine light would turn on. However, you might be able to get a tune to correct this.

Correct on the catalysts, but the '97 were level I OBDII and did not monitor the evaporative system. It would still be advisable to use the evap for vapor management, however. A '97 CVPI would have ABS but not Traction Control and therefore would not be a problem in your truck application.

My train of thought would be that a 351W would have a lot more torque, couples to a bunch of cheap trannys and could be cheaply modified by a Goober with a wrench. But that's your decision to make!

Best Luck,

Well I was under the impression the CVPIs that year were higher in HP than that. I can definately build a 302 or 351 for less money and hassle with more HP. I liked the idea of the Mod Motor to be more consistant in Bracket racing. If it were 250 or more I would re-consider. The Mustang drive trains go for more money than they should in my opinion. I found a Mark VIII 4.6 4V for 950.00 but no tranny and it would have been a bigger hassle.

I am most interested in build a Cleavor (351W block with Cleveland Heads). It seems a great way to get decent power for not too much money from a Ford. I keep tossing the project around in my head and sometimes think of just build the Flathead thats in it. They are getting rare but now days are not cheap to re-build. I will be in the 3k range for the engine in which I can build a nice 302/351 for that money with a lot more HP.

Decisions.

1998 was the first year for PI heads in the Mustang, the Crown Vic didn't get them until 2001.

The reason for the 250 Hp now is the PI heads in 2001, and the Marauder airbox and maf in 2004 (only in CVPIs)

are you sure about that? 98 model year cvpi had a horsepower jump and i think it was due to the pi heads...........???

[ex00p71]

Yup.

Yea he is right^^ My 99' CVPI had 215HP. 2001 was the first year.

thanks for the info.

[RoyLPita]

The guy who I am getting my CV from has a 5.4 V8 with the PI heads. Maybe that could be something to install into your truck.

[Hotraudmerc]

I agree if I could find a complete donor truck or ultimately a Navigator. The mod motors are still very pricey even after 12 plus years of being made.
