Pete is a very experienced dyno operator. One change at a time is the only way to find out if something works (or doesn't). Your right, it would make a very stout street/strip motor.
Epic small block Mopar moment. I think Your new build will make more torque than Pete's. Terrific channel, been watching for awhile: keep up the good work!
100hp short of a modern supercharger hellcat with a carbed small block is impressive! The crazy part is you can build those heads even more so it’s not even maxed out yet.
This looks like a great motor! I recently had a Mopar 408 built by a guy in Alberta, Canada. What a disaster it is. Turns out he didn't even bench run the motor before shipping it, never mind a dyno! Only have 350 miles on it and there are oil leaks!! Took it for a 50 mile drive the other day and and oil was spraying onto the inside of the hood. Also it came home driving choppy!! I'm 2000 miles from the guy so shipping it back is useless. I should have asked more questions before buying...
Could you give me a build sheet for this engine obviously i read they dont make the heads anymore but cam crank rods and pistons and cc of heads. Or what woud it take for your shop to build one for me
This one’s of Pete’s motors. He’s builds top and uses a couple guys for short blocks after he selects parts. Lots of other motor combos on channel! Thanks for watching
Looks like you need a new stall converter. This makes peak torque a bit lower than my engine. Driving with 5000 stall on the street is no problem if converter is built right!
@@SimpsonsSpeedShop sorry I’m not up to date, no time with my hands dirty most of the time ;-) I remember that you had some problems, was sure it’s your new build.
Nice smoke for an iron cylinder head with origins that predate electricity. Probably pick up another 8 to 10 numbers with a Meziere electric water pump.
A very impressive engine, indeed! Thoughs heads are something else. Unfortunitly they are unobtainium in Oz. Blocks are rare, Well 360's are. . They maybe a few skattered in the rural backwaters but how to know/find? My problem. You like Trick Flow heads, Scott? Have a good one. Adam.
W2 stuff hard to find. Indy still makes w2 stuff. Check them out I guess. Or check out my 414 Stroker vid with trick flow heads. Every thing off the shelf from summit
Do you sell big block mopar performance valve covers? I need valve covers that will fit on Trickflow heads and over mechanical Harland sharp rockers. If so can I get contact information?
I'm actually just a province over from you in Alberta so awesome to see other mopars like mine close by! Question im curious if the carb has annular or downleg boosters? I have a 408 also with a 1050 quick fuel downleg booster but could swap with a friends annular(exact same carb otherwise) so trying to figure if it will he worth it or not. He's also selling the car its on so i probably wont be able to test it. I built and tuned his 408 which runs great how it is.
This carb has downlwgs boosters, I haven’t done/seen a good comparison between the 2 styles but people say the annular are better. Thanks for watching 👍🏻🇨🇦🍺
I have that manifold and carb set up, with W2’s that flow those kind of numbers at 650. Minimum 2 inch spacer(3 is better), and minimum 11.5 to 1. Probably 40hp/40ftp in that alone.
I'm guessing those are Mopar W2 heads. Did you run a dyno test between the Aluminum Trick Flow vs the Cast W2 Mopar heads? My buddy ran those back in 1973 when they first came out. He ran the oval ports on his 71 Duster 340 with a 1050 Dominator 4 speed. It ran 10.40's in Super Stock H. AHRA.
Not really comparable w2s will decimate trick flows In the hands of someone who knows what they are doing they are a race head with offset rockers. Trick flows are really maxed out as delivered because they aren't an offset rocker head. I've seen w2 365s that are making 650 and still climbing at 7400 rpm when they shut the dyno down different leauge 😳. If you want to break a stock block get an offset rocker head. If you want a great street engine for not too serious coin trick flows or one of the many other ported stock replacement heads are your ticket 600hp is about the max. The others start there 😆
They are great Heads but are you positive he got them in 1973? From all the records I've seen and guys I know who also had them when they came out seems to correlate to 1976 when they were first available to the public. Richard Petty ran them in 75 and one pro stock team with a Dart Sport used them in 74 for testing for Chrysler. And off course later in 78/79 Glidden had some set's(he made his rectangle n closed chamber) which were on his pro stock Arrow . Technically W-2's wouldn't and still aren't legal for Super Stock since they were never available on a factory car. Now the T/A heads were available in 1970 340 six pack's with the offset rockers and later proceeded to the W-2's. Maybe that's what he had?
Hi joe very nice job on your air cleaner would be interested in one the box is from who? them w2 heads are from who? The cam is? Specs.? Nice job pete.
Being as this is 10.5:1, were these pulls done with 91 octane? If so, whatever this recipe is, is the king kong dong NA small block mopar setup and you should be selling them in a crate ready to run.
