410w swap...

94gsl5.0 · May 22, 2009

I posted some of these in the pics page but decided to share a few more here. Especially since it seems 351 swaps cause quite the ruckess these days Finished the swap some time ago (2 years or so), just never really posted about it.

Anybody who wants to do a 351 swap and has access to a block to build... I say do it. Just be prepared to encounter problems.

410w, Vortech YSi, G-force tranny, etc....

On stand with Old S-trim mocked up.

Rockers

In car with YSi

With holes in the hood to clear... Tried my best to fit it under a stock hood... Almost made it.

At the Mustang Roundup 2008

Mid to high 6XX hp and tq on a Mustang Dyno at 10lbs of boost on 92 pump. Not really pushing her hard right now.

As for runnning it at the track... not much of a track guy these days, until i get some more Safety Equipment.

Wow, someone that knows how to build a motor. Nice to see. Glad you didn't go with GT40 heads and a Typhoon intake.

Thanks dude.

Why would there be a problem with a 351 with Gt40 heads and a Typhoon? It will make more than a 302 with the same...

Oh ****, don't get this started again...

That's an awesome setup. What compression are you running? Daily driver?

99FiveOh · May 23, 2009

That's quite a motor you got there. Mind if I ask what it set you back after all said and done?

BlownFiveLiter · May 23, 2009

Now I see why you sold the SQ-trim last year...

8.5:1

I could daily drive it, but it would not be the best idea... lol.

A lot... More than i care to disclose. I got a killer deal on the short block and all the parts but it still was not cheap.

Nice. Glad it could go to a good home

Nice.

So was the SQ-trim on this engine at some point? What kind of power did that make?

I've been thinking about adding a S-trim to mine. I have 10.5:1 compression, so I was thinking 4 to 6 PSI would be the most I want to run with pump gas. I'd be happy with another 60-80 RWHP. I'm just worried that might be maxing out the S-trim and/or my fuel system.

*Waits for Stopsign32v to tell me a S-Trim is a waste of time and money*

410w non roller converted to roller (Link bar lifters)
All forged
Mild Comp supercharger cam (I forget the specs... would have to find my cam card)
Trick flow Highport Race CNC heads 225cc , 70cc combustion chambers
Custom Jesel Pro Series rockers with a 1.8 ratio (To make up for the mild cam)
Spyder intake with A LOT of porting to mate up to the Highports
60lb injectors with a full fuel system
Etc...

The SQ-trim was on their briefly for mock up but i never ran it. The YSi was in the works since the beginning of the build. I was advised by a reputable tuner that a S-trim would not feed the 410 all that well and would be pushing its efficiency range just to make any real boost. Whereupon he sold me a YSi...

Quite the upsell... lol.

However, i am super happy with the big head unit and it's not a lazy blower like some say.

I used to have a 69 Fairlane with a 302....I had no money for aftermarket heads so I had some 351 heads on it that I ported the exhaust.
I swapped in a 351 shortblock using the same heads and Isky 280 mega cam from the 302. I used the same carb and had a dual plane intake on both.
It had alot more power and picked up almost 1 sec in the 1/4 mi. I have no idea what it made on a dyno I never dynoed either combo.

So I had small heads and the car was a lot more fun with a 351 vs a 302.

Oh yeah, It's about time you posted up some pic's!!!

Hey there!

The "Beater" S351 was looking good up at the shop... Hows it handle after the Alignment?

I know... I know... I am a lurker.

ProKiller · May 23, 2009

that is one heck of a kickass motor

It drives great!
I didn't have a chance to take it out on the twisties yet, tomorrow I'll take it out for a cruise.

Yeah, the YSi is definitely the way to go if you want big power. I just think it's more than I need. You can find used S-trims for cheap, and I know they can support the power I want. A friend of mine made well over 600rwhp with one, but I think it peaked around 580-600 before he added meth injection. I'm just afraid that even with 6# on my car it will be pushing it's efficiency range and blowing hot air, which I definitely don't want with 10.5:1 CR.

None of this really matters anyways because I can't afford any mods for a while.

410w swap...
