250Hp 3400

Not necessarily. Cam choice has an enormously huge impact on cylinder pressure. The more overlap you have the less cylinder pressure you will build.

On the contrary, it's the tune. The car has over 540,000 miles on it with it's 3rd engine. The stock TBI 305 was changed over to the TPI and run by a Ford ECM (MAF). Then he went with a 350 and converted the GM TBI ECM to TPI with a MAP. Then he thought he blew the engine and had a 327 short block laying around, but turned out the 350 just broke the timing chain (thinking it was a rod, changed the short block). Using the parts he had made the current engine, this one using the Holley Commander. I'll have to ask, but I believe it's using the stock cam...

Talk about a sleeper. When he starts it, it reminds me of when DOC raced Lighning McQueen on the dirt track in "Cars". Smoke comes barreling out of the pipes, lol. BUT, from a stand-still it will light the tires for nice long way.

He complains about the top end, though. The TPI is capped at about 1100CFM making it a dog after 5k.

Well I'm keeping it simple and Ben simulated about 290hp (crank) with the setup I have going... stock 3400 lower, gasket matched 3500 top end 65mm TB, SS headers, and stock compression which I think works out to 8.5 or 9:1 with the 3500 heads, I'm not sure and I never whissled it.

Either way I'll be pushing N2O on top of that so yeah... 290 crank n/a is a nice starting platform... LOL

Moonwell's making around 240 WHP on a stock 3400 bottom end (9.5:1 SCR), MMS stage 2 cam and a ported 3400 top end/3500 UIM and some longube headers.

That's about 280 crank HP running 13.8's and it still gets over 30 MPG on the highway
