0 528c.i. 610HP V8 HEMI AutomaticConvertible

West Coast Classics are proud to present a rare and no expense spared frame off restored example of this 1970 Dodge Challenger R/T Hemi Convertible clone with a date correct crate 528c.i. 600+HP 8.6L V8 Hemi Mopar engine matched to an automatic 'Torqueflite' Hemi transmission with Posi rear end.
This particular car was born with a 318 V8 engine but now boasts a crate 528 Hemi V8 engine with the date correct 2468330 casting number engine from 1964-71 and a 2881489 original 8 3/4 Mopar 489 Posi 'Sure Grip' rear end. The 426 RB block was introduced to power the big and heavy Chrysler, Dodge and Plymouth intermediates and full size cars in 1964. This street Hemi engine was the ultimate big block after the 375HP 440 cid V8. Chrysler was heavily involved with racing at the time and the Max Wedge engines were doing well on the drag strip but they were not as competitive on the NASCAR circuits. The Wedge just could not breathe as well as their competitors and Chrysler knew that the reintroduced hemispherical combustion chamber cylinder heads for use on the 426 cid RB blocks was the best design for producing the most power. Rather than build a completely new engine from the ground up Chrysler chose to fabricate hemi cylinder heads and use them on their existing RB engine block. The result was the 426 Hemi from which Chrysler built a great variety of hemi-head engines starting in 1964-65.
The drag race hemi engines were different from the circle track engines with each using different intake setups, internal components and with different displacements. The drag engines were offered in 415 & 426 HP versions whilst the circle track engine was rated at 400 HP with a single 4BBL carburetor. Chrysler first used the engine in the most prestigious NASCAR race of all - the Daytona 500. Hemi powered Plymouths took the first 3 positions in the 1964 race and although Ford won 30 races that year compared to Chrysler's 26, it was obvious that Ford's 427 Wedge days were numbered which resulted in Ford building its own hemi engine, the 427 SOHC.
It should be pointed out that the 426 Hemi and other engines used in sanctioned racing were special, low production engines that were never really intended for use on any street vehicle. Indeed the engines were only produced for street cars after NASCAR ruled that if either Chrysler or Ford wanted to race their complex and expensive hemi-head engines then they would have to build a certain amount of street cars with these motors and sell them first to the public. Ford famously declined but Chrysler went ahead and so the legendary 426 street Hemi was born in 1966. Ford eventually did build its own street hemi, the Boss 429, but not until 1969.
This particular car is the recipient of a full frame off restoration with no expense spared and boasts a crate 528c.i. 610HP 8.6L V8 Hemi engine matched to an automatic 'Torqueflite' Hemi transmission and Posi-traction rear end. The car looks very impressive with the desirable 'Shaker Hood' and in it's striking 'Blue' color with a 'White' interior and matching 'White' power soft top. The car was born as a 1970 Challenger Convertible with a 318 V8 engine in 'Bright Red' with High Trim Grade with Bucket seats, full door panels, a 'White' top, 'Light Package'; & the 'Basic Group' which includes Power steering, left remote mirror, AM 'Music Master' radio, 3 spd wipers; Center console with woodgrain, chrome driver side adjustable racing mirror & Power convertible top.
