New build and motor choices
Hey, long time bronco guy new to this forum. I recently bought my 4th Bronco, a 1986 with a 302 and automatic. Not sure on the trans. My goal for this build would be a Bronco speed/ daily driver. I have a few buddies that have Raptors and I am looking to keep up or out perform them. Planning on wrapping the 86 in Fiberwerx Bronco Raptor conversion. Upgrade the suspension with Solo, or AutoFab. But to start the build I need to nail down an engine trans combo. Luckily I have plenty of options.
As previously mentioned the 86 has a 302 already in it. I am not sure about the condition but when the truck was purchased, as with all trucks sold that aren't running "it was recently rebuilt". Other than those words I am not sure on its capabilities or condition as the truck currently has a short and is frying ignitions.
The next option is a 460 that I had rebuilt from a previous build that was never completed. The 460 was bored .30 over heads were ported and treated to a 3 angle valve job, roller rockers, ThunderJet cam, Keith Black flat top Pistons, weiland dual plane stealth intake and a full msd setup. The upside to this engine is the hp potential and I know what it has and that it was built correctly. I also have a rebuilt C6 with a shift kit and an 2000 stall torque converter with a NP205 bolted behind it. The downside to this engine for the purposes of my build I'm guessing would be the extra weight.
The third option is while negotiating this deal the guy who sold me the Bronco daughters boyfriend through in a cut up f150 2wd that once again had a "recently rebuilt " 351w. The truck had been sitting for over a year as the boyfriend had cut everything from the cab back in hopes to cage the rear and three link it. He had set the f150 up for prerunning and had done some legit fab on the truck. The 351 is said to have 408 hp with a mild cam and a few other unspecific mods. The other thing of note is the 351 has a "recently rebuilt" C6 with a manual valve body and a shift kit. Also thrown in was the original E4OD that was behind the 351.
All engines are setup for carbs. I have searched and read enough in the forum to see that the debate between 351 and 460 is never ending. If I went with the 351 I would not be opposed to rebuilding or at least refreshing the engine. It would of course eat into the build. The other thing to consider was my original purpose for buying this project was to drop the 460 that I had sitting in my garage into something and along the way I acquired another option for my particular build.
If I run the 460 I know there is about a 200 lbs weight difference but will that 200 lbs affect performance that much? Also with the 460, I assume it will be easier or already accomplished, with how the 460 has been setup, to out perform the 6.2 Raptor motor.
Just wondering what the collective opinion is on my many options. Thanks for any input.
