Will this motor run in a Mod. if it has been built up and does the bellhousing bolts match the 350's bolt pattern???????

I seen a guy run one in a mod before and he'd turn it till you're teeth would rattle,he always ran the high groove and did win some really dry slick type features.

We just experimented with a 283 bored to 4.020 with a large pop-up piston and 462 double humps with about a 13 to 1 comp ratio. We thought it would work running it in a 2400# mod. Made 2 outings with this motor on a 1/4 mile track. 1st weekend with a 5.67 gear on a heavy track was dog meat out of the turns - no low end but started to come on about the end of the straitaway. Next weekend we drop a 6.00 gear and had the same heavy track condition. still a little sluggish out of the turns but once it came into the power band it did ok. a 6.33 gear would have been good - problem was we blew the motor to pieces on the last lap - Burned the front end of the crank shaft (spun bearings and they were Clevite "H" bearings). Now we have a good trot line weight. We're not going to mess with the small strokes any more - I agree - 355 to 406 is the way to go. We thought we could make it work but it's just not the type of power band I like. Absolutly no low end at all. Probably a good drag raceing project. We spent a lot of time on this and it didn't work for us. Maybe you'll have better luck. I now prefer the CI's!!!!

Hey nut, Just some more info, We also feel we may have ran too much cam - had a 560/545 lift and that probably worked against us on the bottom end torque problem. Another area we feel we may have ******* up was we ran some good roller lifters and no oil restritors (with a high volume oil pump) We may have starved the bottom end of oil which may explain the rosted bottom end on the front main bearings. Rotating assy was stock but balanced and a fluid dampener. I got another one of these and may try again in the future - I love to do stuff eveyone else says can't be done is one of the reasons we tried this. Keep me informed of your results and feel free to contact me with any questions. We'll be very interested in your results. Randy - sidebite252@yahoo.com

There is a reason why everbody else is doing the same thing because it works. Im not saying that you wont get lucky and win a race or two but If you can what could you do with 200 more HP... as usuall just my opinion....Towman

We ran a 302 in our DIRT mod years ago. It ran like a scalded dog but you had to twist it like a crazy thing, in the 7900-8200 range to keep up with the bigger engines.
